APW38HC42A/3A/4A/5A

CMOS Current-Mode PWM Voltage Controller

Features

General Description

•

Ultralow start-up current (25µA typical)

The APW38HC4XA family are fixed frequency, high

performance, current-mode PWM controller with 1.2

A drive current capability. Undervoltage lockout cir-

cuitry allows the APW38HC42A and APW38HC44A

versions to start up at 14.5V and operate down to

9V, and the APW38HC43A and APW38HC45A ver-

sions start at 8.4V with operateion down to 7.6V. All

versions operate up to 24V. The ultra low start-up

current 25µA (typical), and operating current 2mA

(typical) have been designed to improve the converter

efficiency. High output driving capability up to 1.2A

ensures the fast switching to minimize the switching

losses. The APW38HC4XA features a trimmed and

temperature compensated oscillator discharge cur-

rent and bandgap reference. APW38HC4XA is avail-

able in both 8-pin plastic DIP and SOP packages.

Low operating current (2mA typical)

Fast output rise/fall times :

−15ns rise/10ns fall

•

High output drive (1.2A peak current)

CMOS outputs with rail-to-rail swing

Current-mode operation up to 1MHz

Trimmed 5V bandgap reference

Pin-to-pin compatible with MIC38HC4X

Trimmed oscillator discharge current

UVLO with hysteresis

Low cross-conduction currents
