Description

The NCV97310 is 3−output regulator consisting of
a low−Iq battery−connected 3 A 2 MHz non−synchronous
switcher and two low−voltage 1.5 A 2 MHz synchronous
switchers; all using integrated power transistors.

The high−voltage switcher is capable of converting
a 4.1 V to 18 V battery input to a 5 V or 3.3 V output at
a constant 2MHz switching frequency, delivering up to 3A.
In overvoltage conditions up to 36 V, the switching
frequency folds back to 1 MHz; in load dump conditions up
to 45 V the regulator shuts down.

The output of the battery− connected buck r egulator serves
as the l ow v oltage i nput f or t he 2 s ynchronous s witchers. E ach
downstream output is adjustable from 1.2 V to 3.3 V, with
a 1.5 A current limit and a constant 2 MHz switching
frequency. Each switcher has independent enable and reset
pins, giving extra power management flexibility.

For low−Iq operating mode the low−voltage switchers are
disabled, and the standby rail is supplied by a low−Iq LDO
(up to 150 mA) with a typical Iq of 30 mA. The LDO
regulator is in parallel to the high−voltage switcher, and is
activated when the switcher is forced in standby mode.

All 3 SMPS outputs use peak current mode control with
internal slope compensation, internally−set soft−start,
battery undervoltage lockout, battery overvoltage
protection, cycle−by−cycle current limiting, hiccup mode
short−circuit protection and thermal shutdown. An error flag
is available for diagnostics.

Operational Guidelines

1. Connect a dc input voltage, within the 6.0 V to 36
V range, between VBAT and GND.

2. Connect a load (< 150 mA) between VOUT1 and
GND

3. Connect a dc enable voltage, within the 2.0 V to
36 V range, between EN and GND. This will
enable the internal LDO for low Iq mode. You
may use jumper J1 to connect EN directly to
VBAT.
a. The VOUT1 signal should be 5.0 V.
b. The VOUT2 signal should be disabled

(regardless of EN2 state) and read 0 V.

c. The VOUT3 signal should be disabled

(regardless of EN3 state) and read 0 V.

4. Connect a dc enable voltage, within the 2.0 V to
36 V range, between STBYB and GND. This will
exit low Iq mode and power up switcher 1. You
may use jumper J2 to connect STBYB directly to
VBAT.

The VOUT1 signal should still be 5.0 V. You
may now add a higher load to VOUT1.

NCV97310MW50GEVB

5. Connect a dc enable voltage, within the 2.0 V to
6 V range, between EN2 and GND. This will
power up switcher 2. You may use jumper J4 to
connect EN2 directly to VOUT1.

The VOUT2 signal should be 3.3 V.

6. Connect a dc enable voltage, within the 2.0 V to
6 V range, between EN3 and GND. This will
power up switcher 3. You may use jumper J3 to
connect EN3 directly to VOUT1.

The VOUT3 signal should be 1.2 V.

The spread spectrum used in the NCV97310 is an
“up−spread” technique, meaning the switching frequency is
spread upward from the 2.0 MHz base frequency. For
example, a 5 % spread means that the switching frequency
is swept (spread) from 2.0 MHz up to 2.1 MHz in a linear
fashion – this is called the modulation depth. The rate at
which this spread takes place is called the modulation
frequency. For example, a 10 kHz modulation frequency
means that the frequency is swept from 2.0 MHz to 2.1 MHz
in 50 ms and then back down from 2.1 MHz to 2.0 MHz in
50 ms.

Spread Spectrum

In SMPS devices, switching translates to higher
efficiency. Unfortunately, the switching leads to a much
noisier EMI profile. We can greatly decrease some of the
radiated emissions with some spread spectrum techniques.
Spread spectrum is used to reduce the peak electromagnetic
emissions of a switching regulator.

The modulation depth and modulation frequency are each
set by 2 external resistors to GND. The modulation
frequency can be set from 5 kHz up to 50 kHz using a resistor
from the RMOD pin to GND. The modulation depth can be
set from 3% up to 30% of the nominal switching frequency
using a resistor from the RDEPTH pin to GND. Please see
the curves below for typical values:

Spread spectrum i s a u t o m a t i c a l l y t u r n e d o ff when there is
a short to GND or an open circuit on either the RMOD pin
or the RDEPTH pin. Please be sure that the ROSC pin is an
open circuit when using spread spectrum.
