Regulating Pulse Width Modulator

FEATURES

8 To 35V Operation

DESCRIPTION

•

The UC1526 is a high performance monolithic pulse width modulator

circuit designed for fixed-frequency switching regulators and other

power control applications. Included in an 18-pin dual-in-line pack-

age are a temperature compensated voltage reference, sawtooth os-

cillator, error amplifier, pulse width modulator, pulse metering and

setting logic, and two low impedance power drivers. Also included

are protective features such as soft-start and under-voltage lockout,

digital current limiting, double pulse inhibit, a data latch for single

pulse metering, adjustable deadtime, and provision for symmetry cor-

rection inputs. For ease of interface, all digital control ports are TTL

and B-series CMOS compatible. Active LOW logic design allows

wired-OR connections for maximum flexibility. This versatile device

can be used to implement single-ended or push-pull switching regu-

lators of either polarity, both transformerless and transformer cou-

pled. The UC1526 is characterized for operation over the full military

temperature range of -55°C to +125°C. The UC2526 is characterized

for operation from -25°C to +85°C, and the UC3526 is characterized

for operation from 0° to +70°C.
