NSOT-25 Package

The XC9301/02 series are step-up/down DC/DC converter controller ICs

with fast, low ON resistance drivers built-in. A versatile, large output

current, step-up/down DC/DC converter can be realised using only 4

basic external components - transistors, coils, diodes and capacitors.

Output voltage is selectable in 0.1V steps within a 2.4V ~ 6.0V ( ± 2.5%

accuracy) range and switching frequency is set at 180kHz or 300KHz.

The XC9302 series switches from PWM to PFM control during light loads

and the series offers high efficiencies from light loads through to large

output currents.

Soft-start time is internally set to 10 msec which offers protection against

rush currents when the power is switched on and also against voltage

overshoot.

During shutdown (CE pin = L), consumption current can be reduced to

as little as 0.5µA or less.
