DESCRIPTION

The UCC28610 brings a new level of performance and reliability to the AC/DC consumer power supply solution.

 

A PWM modulation algorithm varies both the switching frequency and primary current while maintaining discontinuous or transition mode operation over the entire operating range. Combined with a cascoded architecture, these innovations result in efficiency, reliability, and system cost improvements over a conventional flyback architecture.

 

The UCC28610 offers a predictable maximum power threshold and a timed response to an overload, allowing safe handling of surge power requirements. Overload fault response is user-programmed for retry or latch-off mode. Additional protection features include output overvoltage detection, programmable maximum on-time, and thermal shutdown.

 

ABSOLUTE MAXIMUM RATINGS(1)

All voltages are with respect to GND, –40°C < TJ = TA < 125°C, all currents are positive into and negative out of the specified terminal (unless otherwise noted)

(1) These are stress ratings only. Stress beyond these limits may cause permanent damage to the device. Functional operation of the device at these or any conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute maximum rated conditions for extended periods of time may affect device reliability

(2) Voltage on VGG is internally clamped. The clamp level varies with operating conditions. In normal use, VGG is current fed with the voltage internally limited

(3) In normal use, MOT, CL, ZCD, and FB are connected to resistors to GND and internally limited in voltage swing
