Description

The UCC28600D is a 8-pin Quasi Resonant Flyback Green Mode Controller with advanced energy features to meet stringent world-wide energy efficiency requirements. UCC28600 integrates built-in advanced energy saving features with high-level protection features to provide cost-effective solutions for energy-efficient power supplies. It incorporates frequency fold-back and green-mode operation to reduce the switching losses at light-load and no-load conditions. As the load increases, the 40kHz switching will become consistent and the controller will transition to frequency fold-back mode (FFM), where the peak primary current is held constant and the switching frequency is modulated from 40 up to 130kHz, in order to maintain regulation.
Green-mode controller with advanced energy saving features
Quasi-resonant mode operation for reduced EMI and low switching losses
Low standby current for minimum system no- load power consumption
Low start-up current (25µA maximum)
Programmable line and load over-voltage protection
Internal over-temperature protection
Current limit protection
Cycle-by-cycle power limit
Primary-side over-current hiccup restart mode
1A sink, -0.75A source TrueDrive™ gate drive output
Programmable soft-start
Green-mode status pin (PFC disable function)
Green product and no Sb/Br
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
