NCP1203D60R2 Description

Short technical summary and product information.

The NCP1203D60R2 from On Semiconductor is a PWM current-mode controller optimized for universal off-line power supply applications. It integrates a high-voltage startup current source and features auto-recovery internal output short-circuit protection, extremely low no-load standby power, and adjustable skip-cycle capability.

 

This controller operates with an internally fixed switching frequency of 60kHz, supporting up to 80% duty cycle. It requires a supply voltage between 7.8V and 16V, with a typical startup voltage of 12.8V. The device includes fault protection for over load, over temperature, and short circuit conditions.

 

Housed in an 8-SOIC package, the NCP1203D60R2 is suitable for surface mount applications. Its design facilitates the implementation of compact switchmode power supplies, making it an excellent candidate for AC-DC adapters and battery chargers.

 

Key features include current-mode control with inherent pulse-by-pulse control, internal leading edge blanking, and a peak current capability of 250 mA. The device also offers a temperature shutdown with hysteresis for robust power supply design.
