Description and Introduction

PWM Current-Mode Controller for Free Running Quasi-Resonant Operation The **NCP1207ADR2G** is a high-performance pulse-width modulation (PWM) current-mode controller designed for offline power supply applications. Manufactured by ON Semiconductor, this integrated circuit (IC) is widely used in switch-mode power supplies (SMPS) due to its efficiency, reliability, and advanced protection features.  

Operating with a fixed-frequency architecture, the NCP1207ADR2G ensures stable performance across varying load conditions. It incorporates an internal 8.0 ms timer for auto-recovery overload protection, reducing the risk of system failure during fault conditions. The device also features a built-in brown-out detection mechanism, enhancing safety in low-input voltage scenarios.  

With a low standby power consumption and a dynamic self-supply capability, the NCP1207ADR2G eliminates the need for an auxiliary winding in certain configurations, simplifying design and reducing component count. Its current-mode control ensures precise regulation and fast transient response, making it suitable for applications such as AC-DC adapters, auxiliary power supplies, and industrial power systems.  

Housed in an SOIC-8 package, the NCP1207ADR2G offers a compact footprint while maintaining robust thermal performance. Engineers favor this IC for its balance of cost-effectiveness and advanced functionality in power conversion designs.
