Description
28W 12V SMPS Demo Board with ICE2QR1080GAN-DEMO-2QR1080GThe CoolSET™-Q1 series (ICE2QRxx80Z) is the first generation ofquasi-resonant integarted power ICs. It is optimized for off-lineswitch mode power supply applications such as LCD monitor, DVDR/W, DVD Combo, Blue-ray DVD, set top box, etc. Operting theMOSFET switch in quasi-resonant mode, lower EMI, higherefficiency and lower voltage stress on secondary diodes areexpected for the SMPS. Based on the BiCMOS technology, theCoolSET™-Q1 series has a wide operation range (up to 25 V) of ICpower supply and lower power consumption. It also offers manyadvantages such as: a quasi-resonant operation till very low loadincreasing the average system efficiency compared to otherconventional solutions; the Active Burst Mode operation enablesultra-low power consumption at standby mode with small andcontrollable output voltage ripple.
Features
800 V avalanche rugged CoolMOS™ with built-in startup cell
- Quasiresonant operation till very low load
- Active burst mode operation for low standby input power (< 100mW)
- Digital frequency reduction with decreasing load for reducedswitching loss
- Built-in digital soft-start
- Foldback point correction and cycle-by-cycle peak currentlimitation
- Maximum on/off time limitation
- Auto restart mode for VCC Overvoltage and Undervoltageprotections
- Auto restart mode for overload protection
- Auto restart mode for overtemperature protection
- Latch-off mode for adjustable output overvoltage protectionand transformer short-winding protection
Typical applications
- Adapter/Charger, Blue Ray/DVD player, Set-top Box, Digital Photo Frame
- Auxiliary power supply of Server, PC, Printer, TV, Home theater/Audio System, White Goods, etc
