UCC28610D 12-65W Green-mode Flyback Power Supply Controller
Datasheet
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.
Features :
- Cascoded Configuration Allows Fully Integrated Current Control Without External Sense Resistor
- Fast Start Up With Low Standby Power Achieved by Cascode Configuration
- Frequency and Peak Current Modulation for Optimum Efficiency Over Entire Operating Range
- Green-Mode (GM) Burst Switching Packets Improve No-Load Efficiency
- Advanced Overcurrent Protection Limits RMS Input and Output Currents
- Thermal Shutdown
- Timed Overload With Retry or Latch-Off Response
- Programmable Opto-Less Output Over-Voltage Protection
- Fast Latched Fault Recovery
- 8-Pin SOIC Package and 8-Pin PDIP Lead-Free Packages
