SG3524N (TEXAS INSTRUMENTS)

The SG3524N is a Regulating Pulse-Width Modulator incorporates all the functions required in the construction of a regulating power supply, inverter or switching regulator on a single chip. They also can be used as the control element for high-power-output applications. The SG3524N designed for switching regulators of either polarity, transformer-coupled DC-to-DC converters, transformer less voltage doublers and polarity-converter applications employing fixed-frequency, pulse-width modulation (PWM) techniques. The complementary output allows either single-ended or push-pull application. Each device includes an on-chip regulator, error amplifier, programmable oscillator, pulse-steering flip-flop, two uncommitted pass transistors, a high-gain comparator and current-limiting and shutdown circuitry.
