FEATURES

DESCRIPTION

•

Reduced Supply Current

The UC1526A Series are improved-performance pulse-width modu-

lator circuits intended for direct replacement of equivalent non- “A”

versions in all applications. Higher frequency operation has been

enhanced by several significant improvements including: a more ac-

curate oscillator with less minimum dead time, reduced circuit de-

lays (particularly in current limiting), and an improved output stage

with negligible cross-conduction current. Additional improvements

include the incorporation of a precision, band-gap reference gener-

ator, reduced overall supply current, and the addition of thermal

shutdown protection.

Oscillator Frequency to 600kHz

Precision Band-Gap Reference

7 to 35V Operation

Dual 200mA Source/Sink Outputs

Minimum Output Cross-Conduction

Double-Pulse Suppression Logic

Under-Voltage Lockout

Along with these improvements, the UC1526A Series retains the

protective features of under-voltage lockout, soft-start, digital cur-

rent limiting, double pulse suppression logic, and adjustable

deadtime. For ease of interfacing, all digital control ports are TTL

compatible with active low logic.

Programmable Soft-Start

Thermal Shutdown

TTL/CMOS Compatible Logic Ports

5 Volt Operation (VIN = VC = VREF = 5.0V)

Five volt (5V) operation is possible for “logic level” applications by

connecting VIN, VC and VREF to a precision 5V input supply. Consult

factory for additional information.
