NCP1207APG Description

Short technical summary and product information.

The NCP1207APG from ON Semiconductor is a PWM current-mode controller optimized for free-running quasi-resonant operation. This device ensures borderline/critical conduction mode across various load and line conditions, minimizing drain voltage switching.

 

Key features include a maximum operating frequency of 200kHz, an output current capability of 500mA, and a peak current capability of 500mA. It supports a wide operating supply voltage range of 10.6V to 20V. The controller integrates auto-recovery overcurrent protection and latching overvoltage protection for enhanced reliability.

 

Designed for isolated flyback converters, the NCP1207APG simplifies transformer design with its Dynamic Self-Supply (DSS) feature, eliminating the need for an auxiliary winding in many applications. It is housed in an 8-PDIP through-hole package, suitable for various power supply designs.

 

This component operates within a temperature range of -40°C to 125°C. It is specified with a typical fall time of 20 ns and a typical rise time of 40 ns. The device is RoHS3 compliant and has a Moisture Sensitivity Level (MSL) of 1.
