NCP1012APL065R2G

AC DC Converters, Offline Switchers Overview

The NCP1012APL065R2G is a monolithic switching regulator from onsemi, designed for low standby power applications. It integrates a high-voltage current source and a current-mode PWM controller into a single package. The device operates with a fixed frequency of 65 kHz and supports a maximum output current of 1.25 A. It features an internal oscillator and includes protection mechanisms such as cycle-by-cycle current limiting and thermal shutdown. The component is housed in a 7-pin PDIP package, suitable for through-hole mounting, and is rated for operation up to +150°C.

AC DC Converters, Offline Switchers Procurement Notes

Verify the exact suffix against official datasheets, as variations exist within the NCP1012 family. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Check for End-of-Life (EOL) notices or Production Change Notices (PCN) prior to procurement. Ensure the specific package type matches the design requirements.

AC DC Converters, Offline Switchers Selection Notes

Select this component for applications requiring integrated high-voltage startup and low quiescent current. Compare pinout compatibility with existing designs if replacing older variants. Verify that the 65 kHz switching frequency aligns with transformer specifications. Ensure the thermal management strategy accommodates the +150°C junction temperature rating.

AC DC Converters, Offline Switchers Part Context

This part belongs to the NCP1012 series of monolithic switchers. These devices are engineered for cost-effective, high-reliability offline power supplies. The series typically combines the power switch and control logic to minimize external component count. It is distinct from the NCP1216 and NCP1239 families, which are controllers rather than integrated switchers.
