General Description
The AAT1217 a high efficiency, synchronous, fixed
frequency, step-up converter designed for singlecell or dual-cell alkaline, NiMH, or NiCd batterypowered applications. The high 1.2MHz switching
frequency and completely integrated control circuitry minimize the total solution footprint area
while maintaining excellent regulation, ripple, and
transient response throughout the full load range.
Pulse skipping mode operation and low quiescent
current allow the AAT1217 to maintain high efficiency performance for light load and sleep mode
conditions. With a 1.2A peak switch current limit,
the AAT1217 is capable of delivering 100mA to the
load from a single AA cell or up to 400mA from dual
AA cells. The AAT1217 has a 0.85V start-up voltage with operation down to 0.5V.
The AAT1217 is available in a Pb-free, space-saving low profile (1mm) 6-pin TSOT23 package and
is rated over the -40°C to +85°C ambient temperature range.

Synchronous Step-Up Converter
Functional Description
The AAT1217 is a synchronous step-up DC-DC converter. It utilizes internal MOSFET switches to
achieve high efficiency over the full load current
range. It operates at a fixed switching frequency of
1.2MHz, and uses the slope compensated current
mode pulse width modulation (PWM) architecture.
1V; the typical start-up voltage is 0.85V.
Synchronous Rectification
The AAT1217 integrates a synchronous rectifier to
improve efficiency as well as to eliminate the need
The device can operate with an input voltage below
for an external Schottky diode. The synchronous
rectifier is used to reduce the conduction loss contributed by the forward voltage of an external
Schottky diode. The synchronous rectifier is realized by a P-channel MOSFET (PMOS) with gate
1217.2007.07.1.0 7
control circuitry that incorporates relatively complicated timing concerns. An external Schottky diode
is required when the output voltage is greater than
4.5V.
Low Voltage Start-Up
The AAT1217 can start-up with supply voltages
down to 0.85V. During start-up, the internal low
voltage start-up circuitry controls the internal
NMOS switch. The AAT1217 leaves the start-up
mode once V

Current Mode Operation
The AAT1217 is based on a slope compensated
current mode PWM control topology. It operates at
a fixed frequency of 1.2MHz. At the beginning of
each clock cycle, the main switch (NMOS) is turned
on and the inductor current starts to ramp. After the
maximum duty cycle or the sense current signal
equals the error amplifier (EA) output, the main
switch is turned off and the synchronous switch
(PMOS) is turned on. This control topology features cycle-by-cycle current limiting which can prevent the main switch from overstress and the external inductor from saturating.
Pulse Skipping Mode Operation
At very light load, the AAT1217 automatically
switches into pulse skipping mode operation to
improve efficiency. During this mode, the PWM
control will skip some pulses to maintain regulation.
If the load increases and the output voltage drops,
the device will automatically switch back to normal
PWM mode and maintain regulation.
Anti-Ringing Control
An anti-ringing circuitry is included to remove the
high frequency ringing that appears on the SW pin
when the inductor current goes to zero. In this
case, a ringing on the SW pin is induced due to
remaining energy stored in parasitic components of
switch and inductor. The anti-ringing circuitry
clamps the voltage internally to the battery voltage
and therefore dampens this ringing.
Application Information
Adjustable Output Voltage
An external resistor divider is used to set the output
voltage. The output voltage of the switching regulator (V
Table 1 lists the recommended resistor values for
particular output voltage settings.
Table 1: Resistor Selection for Output Voltage
Fixed Output Voltage
AAT1217 has two fixed output voltage options:
3.3V and 5V. An internal resistor divider is connected to the FB pin inside the package which eliminates the need for external feedback resistors.
When designing with the fixed output voltage
option, remember to leave the FB pin open; otherwise the output voltage will be affected. However, a
feed-forward capacitor can still be added between
the FB and VOUT pins to enhance the control loop
performance.

that are suitable for typical AAT1217 applications.
AAT1217
600mA, 1.2MHz, Micropower
Synchronous Step-Up Converter
Input Capacitor
A surface mount 4.7µF or greater, X5R or X7R,
ceramic capacitor is suggested for the input capacitor. The input capacitor provides a low impedance
loop for the edges of pulsed current drawn by the
AAT1217. Low ESR/ESL X7R and X5R ceramic
capacitors are ideal for this function. To minimize
stray inductance, the capacitor should be placed
as close as possible to the IC. This keeps the high
frequency content of the input current localized,
minimizing EMI and input voltage ripple. Always
examine the ceramic capacitor DC voltage coefficient characteristics to get the proper value. For
example, the capacitance of a 10µF, 6.3V, X5R
ceramic capacitor with 5.0V DC applied is actually
about 6µF.
A laboratory test set-up typically consists of two long
wires running from the bench power supply to the
evaluation board input voltage pins. The inductance
of these wires, along with the low-ESR ceramic input
capacitor, can create a high Q network that may
affect converter performance. This problem often
becomes apparent in the form of excessive ringing
in the output voltage during load transients which
can produce errors in loop phase and gain measurements. Since the inductance of a short printed
circuit board (PCB) trace feeding the input voltage is
significantly lower than the power leads from the
bench power supply, most actual applications do not
exhibit this problem. In applications where the input
power source lead inductance cannot be reduced to
a level that does not affect the converter performance, a high ESR tantalum or aluminum electrolytic
capacitor should be placed in parallel with the low
ESR, ESL bypass input ceramic capacitor. The introduction of the high ESR capacitor dampens the high
Q network and stabilizes the AAT1217.

Output Capacitor
The output capacitor limits the output ripple and provides holdup during large load transitions. A 4.7µF to
10µF, X5R or X7R, ceramic capacitor is suggested
for the output capacitor. Typically the recommended
capacitor range provides sufficient bulk capacitance
to stabilize the output voltage during large load transitions and has the ESR and ESL characteristics
necessary for low output voltage ripple.
In addition, the output voltage droop during load
transient is dominated by the capacitance of the
ceramic output capacitor. During a step increase in
load current, the ceramic output capacitor alone
supplies the load current until the loop responds.
Within several switching cycles, the loop responds
and the inductor current increases to match the
load current demand. Larger output capacitor values help to reduce the voltage droop during large
load current transients.
External Diode Selection
An external Schottky diode is required when the
output voltage is above 4.5V. The Schottky diode is
optional for output voltages ≤ 4.5V, but can
improve efficiency by about 2% to 3%.
Load Disconnect in Shutdown
In conventional synchronous step-up converters, a
conduction path exists from input to output through
the backgate (body diode) of the P-channel MOSFET during shutdown. Special application circuitry
can disconnect the load from the battery during
shutdown (see Figure 1).
PCB Layout Guidance
The AAT1217 typically operates at 1.2MHz. This is a
considerably high frequency for DC-DC converters.
PCB layout is important to guarantee satisfactory
performance. It is recommended to make traces of
the power loop, especially where the switching node
is involved, as short and wide as possible. First of
all, the inductor, input and output capacitor should
be as close as possible to the device. Feedback and
shutdown circuits should avoid the proximity of large
AC signals involving the power inductor and switching node. The optional rectifier diode (D1 in Figure
1) can improve efficiency and alleviate the stress on
the integrated MOSFETs. The diode should also be
close to the inductor and the chip to form the shortest possible switching loop. While the two-layer PCB
shown in Figures 2 and 3 is enough for most applications, large and integral multi-layer ground planes
