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.
