description (continued)
Output 1 (OUT1) can deliver a maximum of 40 mA, from a 1-V input, with output 2 (OUT2) not loaded. OUT2 can deliver a maximum of 20 mA, from a 1-V input, with OUT1 not loaded. Both outputs can be loaded in the same time, but the total output current of the first voltage doubler must not exceed 40 mA. For example, the load at OUT1 is 20 mA and the load at output 2 is 10 mA.
The devices operate in the newly developed LinSkip mode. In this operating mode, the device switches seamlessly from the power saving, pulse-skip mode at light loads, to the low-noise, constant-frequency linear-regulation mode, once the output current exceeds the device-specific output current threshold.
A power-good function supervises the output voltage of OUT2 and can be used for power up and power down sequencing. Power good (PG) is offered as either open-drain or push-pull output.

SLVS302A – DECEMBER 2000 – REVISED MARCH 2001
detailed description
operating principle
The TPS6030x charge pumps are voltage quadruplers that provide a regulated 3.3-V or 3.0-V output from a
0.9-V to 1.8-V input. They deliver a maximum load current of 20 mA. Designed specifically for space critical battery powered applications, the complete converter requires only five external capacitors and enables the design to use low-cost, small-sized, 1-µF ceramic capacitors. The TPS6030x circuits consist of an oscillator, a voltage reference, an internal resistive feedback circuit, an error amplifier, two charge pump stages with MOSFET switches, a shutdown/start-up circuit, and a control circuit.
shutdown
Driving EN low disables the converter. This disables all internal circuits, reducing input current to only 0.05 µA. Leakage current drawn from the output pins OUT1 and OUT2 is a maximum of 1 µA. The device exits shutdown once EN is set high (see start-up procedure described below). The typical no-load, start-up time is 400 µs. When the device is disabled, the load is isolated from the input. This is an important feature in battery operated products because it extends the battery shelf life.
start-up procedure
The device is enabled when EN is set from logic low to logic high. CP1 will first enter a dc start-up mode during which the capacitor on OUT1 is charged up to about V up to about two times V
. CP2 will then follow and charge up the capacitor on OUT2 to about the voltage on
IN
OUT1, after that, it will also start switching and boost up the voltage to its nominal value. EN must not exceed the highest voltage applied to the device.
. After that, it starts switching to boost the voltage further
IN
NOTE:
During start-up with V
= 0 V, the highest voltage is the input voltage.
OUT
power-good detector
The power-good output is an open-drain output on the TPS60300 and TPS60301 or a push-pull output on the TPS60302 and TPS60303. The PG-output pulls low when the output of OUT2 is out of regulation. When the output rises to within 98% of regulation, the power-good output goes active high. In shutdown, power-good is pulled low. In normal operation, an external pullup resistor with the TPS60300 and TPS60301 is typically used to connect the PG pin to VOUT . The resistor should be in the 100-k to 1-M range. If the PG output is not used, it should remain unconnected. Output current at PG (TPS60302, TPS60303) will reduce maximum output current at OUT2.

design procedure
capacitor selection
The TPS6030x devices require only five external capacitors. Their values are closely linked to the required output current and the output noise and ripple requirements. It is possible to only use 1-µF capacitors of the same type.
The input capacitor improves system efficiency by reducing the input impedance and stabilizing the input current.
The minimum required capacitance of the output capacitor (C
) that can be selected is 1 µF . Depending on the
O
maximum allowed output ripple voltage, larger values can be chosen. Table 1 shows capacitor values recommended for low output voltage ripple operation. A recommendation is given for the smallest size.

Figure 20. Typical Operating Circuit
For the maximum output current and best performance, five ceramic capacitors of 1 µF are recommended. For lower currents or higher allowed output voltage ripple, other capacitors can be used. It is recommended that the input and output capacitors have a minimum value of 1 µF. This value is necessary to assure a stable operation of the system due to the linear mode. With flying capacitors lower than 1 µF, the maximum output power will decrease. This means that the device will work in the linear mode with lower output currents.
output filter design
The power-good output is capable of driving light loads up to 5 mA (see Figure 21). Therefore, the output resistance of the power-good pin, in addition with an output capacitor, can be used as an RC-filter.

As given in the data sheet, the thermal resistance of the unsoldered package is R the EVM, a typical thermal resistance of R

Where:

The maximum power dissipation happens with maximum input voltage and maximum output current: At maximum load the supply current is approximately 2 mA.
P
= 1.8 V × (3 × 20 mA + 2 mA) – 3.3 V × 20 mA = 46 mW.
D
With this maximum rating and the thermal resistance of the device on the EVM, the maximum temperature rise above ambient temperature can be calculated:

This means that internal dissipation increases T

The junction temperature of the device must not exceed 125°C. This means the IC can easily be used at ambient temperatures up to:

layout and board space
All capacitors should be soldered as close as possible to the IC. A PCB layout proposal for a two-layer board is shown in Figure 24. Care has been taken to connect all capacitors as close as possible to the circuit to achieve optimized output voltage ripple performance. The bottom layer is not shown in Figure 24. It only consists of a ground-plane with a single track between the two vias that can be seen in the left part of the top layer.
