AC DC Converters, Offline Switchers datasheet and documents for NCP1207PG

NCP1207PG

AC DC Converters, Offline Switchers Overview

The NCP1207PG is a switching controller utilizing Quasi-Resonant Current Mode PWM technology. It supports Flyback topology with one output. The device operates at a switching frequency of 75 kHz and provides a maximum duty cycle of 28.6%. It delivers an output current of 500 mA. The component functions within a supply voltage range up to 18 V, with rise and fall times of 40 ns and 20 ns respectively. It is housed in a PDIP-8 package for through-hole installation and withstands operating temperatures from -40 C to +150 C.

AC DC Converters, Offline Switchers Feature Summary

Combines true current mode modulation with demagnetization detection for critical conduction mode operation.
Features Dynamic Self-Supply (DSS) to simplify transformer design by eliminating auxiliary winding requirements.
Includes internal timer to limit free-run frequency below EMI starting limits and prevent audible noise via burst mode.
Provides permanent latch-off Overvoltage Protection (OVP) and continuous feedback monitoring for overcurrent fault protection.
