XC9301/9302 Series

General Description

PWM, PWM/PFM Switching

Step-Up & Down DC/DC Controller

Features

DETAILS

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 con-

verter can be realised using only 4 basic external components

- transistors, coils, diodes and capacitors.

Output voltage is selectable in 0. V steps within a 2.4V ~ 6.0V

( ± 2.5% accuracy) range and switching frequency is set at

180kHz.

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 pro-

tection 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 0.5

A or less.

Input Voltage Range:

2.0V ~ 10V

Output Voltage Range:

2.4V ~ 6.0V ( ± 2.5% accuracy)

(selectable in 0. V steps)

Oscillation Frequency:

180KHz ( ± 15% accuracy)

Output Current:

more than 250mA (V

=2.4V, V

OUT

=3.3V)

Efficiency:

81% (typ) at 5.0V

78% (typ) at 3.3V
