Product details

Description

The UTC UC3838 provides a CCM switching mixed mode operation for better efficiency performance.

The operation mode stays at CCM at heavy load, and switch to power-saving mode at light load.

The UTC UC3838 is a high performance current mode PWM controller ideally suited for low standby power.
