SG3524F-switching power supply control circuit
DESCRIPTION This monolithic integrated circuit contains all the control circuits for a power inverter or a switching regulator. Included in a 16-pin dual in-line package are the voltage reference, error amplifier, oscillator, pulse width modulator, pulse steering flip-flop, dual alternate output switches and current limit and shutdown circuitry. This device can be used in either polarity of switching regulators, transformer-coupled DC-DC converters, transformer voltage doublers and polarity converters, and other power control applications. The SG3524 is designed for commercial 0°C to +70°C applications
Features • Complete PWM power control circuit • Single-ended or push-pull output • Line and load regulation 0.2%
• 1% maximum temperature change • Total supply current less than 10mA
• Operation beyond 100kHz
