The CoolSET®-Q1 series (ICE2QRxx65G) is the first generation of quasi-resonant controller and CoolMOSTM integrated power IC. Operating the MOSFET switch in quasi-resonant mode, lower EMI, higher efficiency andlower voltage stress on secondary diodes are expected for the SMPS. Based on the BiCMOS technology, the CoolSET®-Q1 series has a wide operation range (up to 25V) of IC power supply and lower power consumption.It also offers many advantages such as quasi-resonant operation till very low load, increasing the higher average system efficiency compared to other conventional solutions, achieving ultra-low power consumptionwith small and controllable output voltage ripple at standby mode with Active Burst Mode operation, etc.
- 650V avalanche rugged CoolMOSTM with built-in startup cell
- Quasi resonant operation till very low load
- Active burst mode operation for low standby input power (< 0.1W)
- Digital frequency reduction with decreasing load for reduced switching loss
- Built-in digital soft-start
- Foldback point correction and cycle-by-cycle peak current limitation
- Maximum on time limitation
- Auto restart mode for VCC over-voltage protection, under-voltage protection, over-load protection and overtemperatureprotection
- Latch-off mode for adjustable output over-voltage protection and transformer short-winding protection
