NCP1652ADR2G

Overview

The NCP1652ADR2G is a high-efficiency single-stage power factor correction and step-down controller manufactured by onsemi. Designed for flyback applications, it integrates PFC and DC-DC functions in a compact package. The device operates with a maximum switching frequency of 250 kHz and supports both continuous conduction mode (CCM) and discontinuous conduction mode (DCM). It features an adjustable output voltage range up to 12 V and can deliver an output current of 800 mA. The controller accepts a supply voltage between 9 V and 28 V, with a typical operating current of 1.4 mA. It is housed in a SOIC-16 package and is rated for operation within a temperature range of -40°C to +125°C.
