Absolute Maximum Ratings
Absolute maximum ratings are the values beyond which the device may be damaged or have its useful life
impaired. Functional operation under these conditions is not implied.
Recommended Operating Conditions
Note 1: Industrial temperature range (–40 to + 85°C) may be special ordered from Fairchild. Please contact your authorized Fairchild
representative for more information.

amplitude of the internal oscillator ramp. When using the IC for 2-step conversion from 5V
input, connect through 100K to ground, which will set the appropriate ramp gain and
synchronize the channels 90 out of phase.
Power Good Flag.
An open-drain output that will pull LOW when VSEN is outside of a
±10% range of the 0.9V reference.
Power Good 2.
When not in DDR Mode: Open-drain output that pulls LOW when the
VOUT 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 VDDQ/2 reference.
Current Limit 2.
When not in DDR Mode, A resistor from this pin to GND sets the current
limit.
Reference
for reg #2 when in DDR Mode. Typically set to VOUT1 / 2.
VCC.
This pin powers the chip as well as the LDRV buffers. The IC starts to operate when
voltage on this pin exceeds 4.6V (UVLO rising) and shuts down when it drops below 4.3V
(UVLO falling).
Normally connected to battery, providing voltage feed-forward to set the
