Microchip Technology, Inc. PWM Controller Voltage Mode +/-1% Ref - pulse width modulator 55 °C to 125 °C SG1524

This monolithic integrated circuit contains all the control circuitry for a regulating power supply inverter or switching regulator. Included in a 16-pin dual-in-line package is the voltage reference, error amplifier, oscillator, pulse width modulator, pulse steering flip-flop, dual alternating output switches and current limiting and shut-down circuitry. This device can be used for switching regulators of either polarity, transformer coupled DC to DC converters, transformer less voltage doubles and polarity converters, as well as other power applications. The SG1524 is specified for operation over the full military ambient temperature range of -55°C to +125°C, the SG2524 for -25°C to +85°C, and the SG3524 is designed for commercial applications of 0°C to +70°C. Additional Features 8V to 40V Operation 5V Reference Reference Line and Load Regulation of 0.4% 100Hz to 300kHz Oscillator Range Excellent External Sync Capability Dual 50mA Output Transistors Current Limit Circuitry Complete PWM Power Control Circuitry Single Ended or Push-Pull Outputs Total Supply Current less than 10mA
