KA3524-Switching Power Supply Controller
Description The KA3524 Regulated PWM contains all the necessary control circuits to implement switching polarity regulators, transformer-coupled DC-DC converters, transformer-polarity and voltage converter multipliers, and other power control applications. This device includes a 5V regulator capable of supplying up to 50mA of external circuitry, control amplifiers, an oscillator, a pulse width modulator, phase split flip-flops, dual alternate output switching transistors, and current limit and shutdown circuitry. Both the regulator output switching transistors and each output are internally current limited and limit junction temperature, aninternal thermal shutdown circuit is employed. ...
Features•Complete PWM power control circuit•Operation over 100KHz•2% frequency stability with temperature•Total quiescent current less than 10mA
• Single-ended or push-pull output • Current limit amplifier provides external component protection • On-chip junction temperature protection against excessive and output current • 5V voltage, 50mA linear regulator output available to the user
