Product Overview
The UCC28630D is a high power Fly-back Converter with primary-side regulation and peak power mode. The powerful gate driver and ability to operate in both CCM and DCM make the device suitable for applications with a wide power range. The peak power mode allows transient peak power delivery up to 200% of nominal rating, with only a 25% peak current increase, maximizing transformer utilization. The transformer bias winding is used to sense output voltage for regulation and for low-loss input voltage sensing. Advanced sampling and processing techniques allow CCM operation and deliver excellent output voltage regulation performance for opto-coupler-less designs at power levels of 100W and above. Advanced light-load modes are deployed to reduce both controller and system power consumption at no load and light load. These modes enable potential system designs to meet 30mW no-load power for power designs up to 30W nominal, 60W peak.
- High-power, primary-side regulation for output voltage and current, no optocoupler required
- Continuous conduction mode and discontinuous conduction mode operation
- Active X-capacitor discharge function
- Adjustable constant-current mode limiting
- Peak-power mode for transient overload
- Shutdown pin interface for external NTC
- Frequency dither to ease EMI compliance
- High gate drive current 1A source and 2A sink
- Low power modes for <30mW system standby
- Best-in-class light load (10%) efficiency >85% for 65W nominal power design
- Green product and no Sb/Br
