NCP1651DR2G Description

Short technical summary and product information.

The NCP1651DR2G from ON Semiconductor is an active power factor correction controller suitable for isolated AC-DC converters. It operates over a wide range of input voltages and is designed for 50/60 Hz power systems. This fixed frequency controller can operate in continuous or discontinuous conduction modes, easing input filter design.

This device provides a low cost, low component count solution for meeting IEC1000-3-2 harmonic requirements for converters in the range of 50 W to 250 W. It drives a flyback converter topology and programs the average input current to follow the line voltage for unity power factor. The NCP1651DR2G utilizes average current mode control (CCM algorithm) to help provide excellent power factor while limiting peak primary current. It also features an internal high voltage startup circuit, overtemperature shutdown, external shutdown, and undervoltage lockout.

The NCP1651DR2G is supplied in a SOIC-16 package and is available on tape and reel. Its proprietary multiplier design ensures more accurate operation compared to conventional analog multipliers. This component is ideal for applications such as high current battery chargers and front ends for distributed power systems.
