SG1526/SG2526/SG3526
REGULATING PULSE WIDTH MODULATOR
DESCRIPTION
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.
