NCP1203P100G Description

Short technical summary and product information.

The NCP1203P100G from ON Semiconductor is a PWM current-mode controller suitable for universal off-line power supplies, featuring standby and short circuit protection. It operates at a fixed 100 kHz switching frequency and offers a maximum duty cycle of 80% with a peak current capability of 250 mA.

 

This controller is housed in an 8-PDIP package and supports through-hole mounting. It includes features like auto-recovery internal output short-circuit protection and extremely low no-load standby power. The operating temperature range is from -40°C to 125°C.

 

Designed for applications such as AC-DC adapters, offline battery chargers, and auxiliary power supplies, the NCP1203P100G facilitates the implementation of compact switchmode power supplies with few external components. Its current-mode control provides inherent pulse-by-pulse control and adjustable skip-cycle capability for improved light-load efficiency.
