PG-DSO-16/12
Features
• 650V avalanche rugged CoolMOS^TM 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 over-
temperature protection
• Latch-off mode for adjustable output over-voltage protection and transformer short-winding protection
Description
The CoolSET^®-Q1 series (ICE2QRxx65G) is the first generation of quasi-resonant controller and CoolMOS^TM
integrated power IC. Operating the MOSFET switch in quasi-resonant mode, lower EMI, higher efficiency and
lower 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 consumption
with small and controllable output voltage ripple at standby mode with Active Burst Mode operation, etc.
Applications
 Adapter/Charger
 LCD monitor, DVD R/W, DVD Combo, Blue-ray/DVD player, Set-top box
 Auxiliary power supply for PC, Printer, TV, Home theater/Audio System, etc.
