NCP1653ADR2G

Overview

The NCP1653ADR2G is a compact, fixed-frequency, continuous conduction mode (CCM) power factor correction (PFC) controller manufactured by onsemi. It operates in follower boost or constant output voltage modes at fixed switching frequencies of 67 kHz or 100 kHz. The device is housed in an SOP-8 package and integrates high safety protection features to minimize external component count.

Feature Summary

• Supports follower boost operation for reduced output voltage and smaller passive components
• Integrates high safety protection features for robust circuit implementation
• Minimizes external component requirements to simplify CCM PFC design

Applications

• Continuous Conduction Mode (CCM) Power Factor Correction boost circuits
• Follower boost applications requiring reduced inductor size
• Compact PFC stage implementations

Procurement Notes

Verify the specific suffix 'ADR2G' against the manufacturer's current datasheet to confirm pinout compatibility and operational frequency selection (67 kHz vs 100 kHz). Ensure the ordering code matches the required package variant and compliance standards before procurement.

Selection Notes

Select this component for designs requiring a simplified CCM PFC topology with minimal external parts. It is suitable for applications where fixed-frequency operation is preferred over variable frequency schemes. Verify that the target switching frequency aligns with the specific sub-model capabilities.

Part Context

This part belongs to the NCP1653 family of power factor controllers designed for CCM boost topologies. It serves as a driver for robust and compact PFC stages, offering an alternative to more complex control schemes by integrating essential functions into a single IC.
