SG1526/SG2526/SG3526  
REGULATING PULSE WIDTH MODULATOR  
DESCRIPTION  
FEATURES  
• 8 to 35 volt operation  
The SG1526 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 package  
are a temperature compensated voltage reference, sawtooth oscillator,  
error amplifier, pulse width modulator, pulse metering and steering logic,  
and two low impedance power drivers. Also included are protective  
features such as soft-start and undervoltage lockout, digital current  
limiting, double pulse inhibit, a data latch for single pulse metering,  
adjustable deadtime, and provision for symmetry correction 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 regulators of either polarity, both  
transformerless and transformer coupled. The SG1526 is characterized  
for operation over the full military ambient junction temperature range of  
-55°C to +150°C. The SG2526 is characterized for operation from -25°C  
to +150°C, and the SG3526 is characterized for operation from 0°C to  
+125°C.  
• 5V reference trimmed to ±1%  
• 1Hz to 350KHz oscillator range  
• Dual 100mA source/sink outputs  
• Digital current limiting  
• Double pulse suppression  
• Programmable deadtime  
• Undervoltage lockout  
• Single pulse metering  
• Programmable soft-start  
• Wide current limit common mode range  
• TTL/CMOS compatible logic ports  
• Symmetry correction capability  
• Guaranteed 6 unit synchronization  
HIGH RELIABILITY FEATURES - SG1526  
♦ Available to MIL-STD-883B and DESC SMD  
♦ Radiation data available  
♦ LMI level "S"processing available
