NCP1032 Datasheet (ON Semiconductor) - Low Power PWM Controller

NCP1032, Low Power PWM Controller

Pin Name Function Description 1 GND IC Ground Ground reference pin for the circuit.

2 CT Oscillator Frequency An external capacitor connected to this pin sets the oscillator frequency up to 1 MHz.

The Selection oscillator can be synchronized to a higher frequency by charging or discharging

NCP1032 Low Power PWM Controller with On-Chip Power Switch The NCP1032 is a miniature high voltage monolithic switching converter with on chip power switch and startup circuits.

It incorporates in a single IC all the active power control logic and protection circuitry required to implement, with minimal external components several switching regulator applications, such as a secondary side bias supply or a low power DC DC converter.

This converter is ideally suited for 24
