It is optimized for off-line switch mode power supply applications such as LCD monitor, DVD R/W, DVD Combo, Blue-ray DVD, set top box, etc. 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 which increases the average system efficiency, Active Burst Mode operation which enables an ultra-low power consumption at standby mode with small and controllable output voltage ripple, etc. Product Highlights • Quasi resonant operation • Active Burst Mode to reach the lowest standby power requirement <100mW@no load • Digital frequency reduction for better overall system efficiency • Integrated 650V avalanche rugged CoolMOS® with startup cell • PB-free lead plating; RoHS compliant Features • 650V avalanche rugged CoolMOS® with built-in startup cell • Quasiresonant 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/off time limitation • Auto restart mode for VCC Overvoltage and Undervoltage protections • Auto restart mode for overload protection • Auto restart mode for overtemperature protection • Latch-off mode for adjustable output overvoltage protection and transformer short-winding protection 85 ~ 265 VAC Snubber Cbus Dr1~Dr4 RCS TL431 Optocoupler Rb1 Rb2 Rc1 Cc1 Cc2 Rovs2 Rovs1 CVCC DVCC DO CO Lf Cf VO CPS Startup Cell CoolSET ®-Q1 CoolMOS ® Wp Ws Wa RVCC CZC RZC2 RZC1 Drain Zero Crossing Block Power Management Cycle-by-Cycle current limitation Active Burst Mode PWM controller Current Mode Control Protections VCC CS Control Unit ZC FB GND |
