UC1108 LOW-POWER OFF-LINE PRIMARY SIDE REGULATION CONTROLLER

The UTC UC1108 is a primary control unit for switch mode charger and adapter applications. The controlled variable is transferred by an auxiliary winding from the secondary to the primary side. The device uses Pulse Frequency Modulation (PFM) method to build discontinuous conduction mode (DCM) flyb.

UC1108 Features

* including Cycle-by-cycle current limiting, output over voltage protection, feedback loop open protection, short circuit protection, leading edge blanking, VCC under voltage lockout, etc.

* FEATURES

* 30mW No-load Input Power

* Primary side control for eliminating opto-coupler and secon
