Description
DDR Mode Control . HIGH = DDR Mode. LOW = two separate regulators operating 180° out
of phase.
Input Voltage . Normally connected to battery, providing voltage feedforward to set the
amplitude of the internal oscillator ramp. When using the IC for two-step conversion from 5V
input, connect through 100K Ω resistor to ground, which sets the appropriate ramp gain and
synchronizes the channels 90° out of phase.
Power Good Flag . An open-drain output that pulls LOW when V SEN is outside a ±10%
range of the 0.9V reference.
Power Good 2 . When not in DDR Mode, open-drain output that pulls LOW when the V OUT is
out of regulation or in a fault condition.
Reference Out 2 . When in DDR Mode, provides a buffered output of REF2. Typically used
as the V DDQ/2 reference.
Current Limit 2 . When not in DDR Mode, a resistor from this pin to GND sets the current
18
ILIM2 / REF2 limit.
Reference for reg #2 when in DDR Mode. Typically set to V OUT1 / 2 .
VCC . This pin powers the chip as well as the LDRV buffers. The IC starts to operate when
28
VCC
voltage on this pin exceeds 4.6V (UVLO rising) and shuts down when it drops below 4.3V
(UVLO falling).
