NCP1366BABAYDR2G Description

Short technical summary and product information.

The ON Semiconductor NCP1366BABAYDR2G is a low-power offline constant current PWM current-mode controller designed for universal-mains flyback applications. It provides primary-side constant current control, eliminating the need for secondary-side components for current regulation. This controller operates in valley-lockout quasi-resonant peak current mode control for high efficiency at nominal loads.

 

Key features include ±10% current regulation, a 560V startup current source, and options for 80 or 110 kHz maximum switching frequency. It incorporates cycle-by-cycle peak current limiting, built-in soft-start, and over/under output voltage protection. The device operates within a wide VCC range of 6.5V to 28V and has low startup current.

 

Packaged in a 7-SOIC (8-SOIC, 7 leads) surface-mount package, the NCP1366BABAYDR2G is suitable for low power AC-DC adapters and USB chargers. It offers internal temperature shutdown for thermal protection and less than 30 mW no-load performance at high line.

 

This isolated flyback controller is designed for applications requiring efficient power conversion up to 20W, simplifying design and reducing component count.
