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.
