DESCRIPTION The IP1526A series of high performance pulse width modulator circuits is a direct replacement for the IP1526 series in all applications and features improved performance in several key areas. Functions included are a temperature pensated voltage reference, sawtooth oscillator, error amplifier, PWM parator, pulse metering and steering logic, and two low impedance power drivers. Also included are protective features such as soft-start, undervoltage lockout, digital current limiting, double pulse inhibit, a data...
