Description

The SG3526 is a high performance pulse width modulator integratedcircuit intended for fixed frequency switching regulators and other power control applications.

Functions of SG3526 is a temperature compensated voltage reference, sawtooth oscillator, error amplifier, pulse width modulator, pulse metering and steering logic, and two high current totem pole outputs ideallysuited for driving the capacitance of power FETs at high speeds. Additional protective features include soft start and undervoltage lockout, digital current limiting, double pulse inhibit, adjustable dead time and a data latch for single pulse metering. All digital control ports are TTL and Bseries CMOS compatible. Active low logic design allows easy wiredOR connections for maximum flexibility. The versatility of this device enables implementation in singleended or pushpull switching regulators that are transformerless or transformer coupled. The SG3526 is specified over ajunction temperature range of 0° to +125°C.
