NCP1377BPG Description

Short technical summary and product information.

The NCP1377BPG from ON Semiconductor is a PWM Current-Mode Controller designed for free-running, quasi-resonant operation. It ensures borderline/critical conduction mode across various load and line conditions, minimizing drain voltage switching.

 

This controller integrates a demagnetization detector and skip cycle capability, allowing it to enter burst mode at low power demands without audible noise. The NCP1377B version supports higher operating frequencies up to 300 kHz.

 

Key features include latched overvoltage protection, auto-recovery short-circuit protection via UVLO crossover, and an internal 1.0 ms soft-start. It operates within a voltage range of 7.5V to 18V and has an operating temperature range of -40°C to 125°C (TJ).

 

The NCP1377BPG is available in a 7-PDIP package and is suitable for through-hole mounting. Typical applications include AC-DC adapters, offline battery chargers, and consumer electronics.
