Product Details
The TOPSwitchGaN IC is an integrated switched-mode power supply that extends the maximum output power of a classic flyback converter to 440 W, offering a simpler alternative to complex resonant and LLC topology. It monitors an analog feedback current at the control input to modulate the variable-frequency variable-current control.
The TOPSwitchGaN flyback controller can operate in continuous conduction mode (CCM) or discontinuous conduction mode (DCM). The controller consists of a frequency-jitter oscillator, a current-limit controller, 5 V regulator on the BYPASS pin, BYPASS undervoltage and overvoltage detection circuit, an input-line sensing circuit, current -limit selection circuitry, over-temperature protection, leading-edge blanking, and a PowiGaN power switch.
Product Highlights
Highly Integrated, Compact Footprint
- 90% average efficiency between 20% and 100% load
- Robust 800 V PowiGaN™ switch provides excellent surge withstand
- Switching frequency up to 150 kHz minimizes transformer size
EcoSmart™ – Energy Efficient
- No-load consumption below 50 mW at 230 VAC
- Up to 200 mW output power for 300 mW input at 230 VAC
Reduced Part Count, Design Flexibility
- Frequency jitter and source potential cooling reduces EMI filter size
- Integrated soft-start reduces start-up stress
- Programmable switching frequency increases design flexibility
- Available in surface-mount for PCB cooling and through-hole for heatsink integration
