PG-DSO-16/12
Features
• 800V 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, cycle-by-cycle peak current limitation and 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
• Lower Vcc turn off threshold
Description
The ICE2QR2280G-1 is derived from CoolSET^TM-Q1. The only difference is it has a lower Vcc turn off threshold.
The CoolSET^TM-Q1 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^TM-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 server, PC, Printer, TV, Home theater/Audio System, etc.
