Infineon ICC80QSGXUMA1, PWM Controller

The Infineon fly back controller is tailored for battery charger application to meet the required performance. It has Quasi-resonant mode (QRM) operation with continuous conduction mode (CCM)-prevention and valley switching discontinuous conduction mode (DCM) in mid to light load. It is also suited for adapter, printer, PC, TV, monitor, set-top box, audio amplifier applications up to 130 W.

Supports on/off control with external pull-down signal
Soft start to reduce component stress during turn-on
External start-up circuit control signal
