AC DC Converters, Offline Switchers datasheet and documents for NCP1201P100G

NCP1201P100G

AC DC Converters, Offline Switchers Overview

The NCP1201P100G is a PWM current-mode controller for universal offline supplies, housed in an 8-PDIP package. It operates at a fixed switching frequency of 100 kHz with a maximum duty cycle of 83%. The device supports flyback topology and features internal fault protection including overcurrent, overtemperature, and short-circuit conditions. It draws power from the high-voltage rail, eliminating the need for an auxiliary winding. The component offers brownout detection and skip-cycle mode for low standby power.

AC DC Converters, Offline Switchers Feature Summary

Eliminates auxiliary winding requirement by self-supplying from the high-voltage rail
Provides permanent output pulse disable upon fault detection until mains power cycles
Features Brownout Detection Protection (BOP) for enhanced reliability
Utilizes skip-cycle mode to maintain efficiency under light load conditions

AC DC Converters, Offline Switchers Applications

Offline AC-DC adapters
Battery chargers
Switchmode Power Supplies (SMPS)

AC DC Converters, Offline Switchers Procurement Notes

Verify component authenticity through authorized channels as this part number is listed as obsolete or end-of-life by the manufacturer. Confirm specific revision status and RoHS compliance details against the latest official datasheet before integration. Ensure design compatibility with the fixed 100 kHz frequency and PDIP-8 package constraints.

AC DC Converters, Offline Switchers Selection Notes

Select this controller for designs prioritizing low standby power and simplified transformer design due to the absence of auxiliary winding requirements. Consider the fixed frequency operation and current-mode control characteristics for applications requiring inherent pulse-by-pulse protection and excellent audio-susceptibility performance.

AC DC Converters, Offline Switchers Part Context

This component belongs to the NCP1201 series, which enhances the previous NCP1200 series by offering reduced optocoupler current and additional brownout detection. It is designed for universal off-line supplies where standby power consumption is a critical parameter, providing efficient protection circuitry and low-power internal structure.
