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.
