PIN FUNCTIONS (DFN/TSSOP)

BYP+ (Pin 15/Pin 17): LDO+ Reference Bypass Pin. Con-

nect a capacitor from BYP+ to GND to reduce LDO+ output

noise. Leave floating if unused.

ADJ+ (Pin 16/Pin 18): Feedback Input for the Positive

Low Dropout (LDO+) Regulator. This pin servos to a fixed

voltage of 1.2V when the control loop is complete.

LDO+(Pin17/Pin19):PositiveLowDropout(LDO+)Output.

This pin requires a low ESR capacitor with at least 2µF

capacitance to ground for stability.

VOUT+(Pin18/Pin20):BoostChargePumpOutputVoltage.

Inconstantfrequencymode(MODE=low)thispinisdriven

to 2 • VIN_P. In Burst Mode operation, (MODE = high) this

pin voltage is regulated to 0.94 • 2 • VIN_P using an internal

burst comparator with hysteretic control.

GND (Exposed Pad Pin 19/Exposed Pad Pin 21): Ground.

The exposed package pad is ground and must be soldered

to the PC board ground plane for proper functionality and

for rated thermal performance.
