CEC Requirement -2 www.active-semi.com
Low Power AC-DC Linear Charger 1) Low cost (< $0.3 PCBA for 5W) 2) Large size & heavy 3) Single line Input 4) Not meeting Green Mode Switching Mode Charger 1) Higher Cost (> $0.5 PCBA for 5W) 2) Universal line input 3) Meet Energy star, blue angel, CEC 4) EMI www.active-semi.com
Switching Mode Charger • RCC 1) Lowest cost 2) Variable Frequency 3) Inconsistent performance • PWM 1) $0.1 – $0.2 more than RCC 2) Fixed frequency 3) Consistent green mode & EMI www.active-semi.com
RCC Charger 1) No PWM IC ($0.1 - $0.2) 2) NPN Switch ($0.025) www.active-semi.com
PWM IC Charger 1) PWM IC + MOSFET ($0.1-0.2 + $0.125) 2) Integrated Switch www.active-semi.com
High Voltage Switch 1) Cost ($0.125 vs 0.025) 2) Efficiency 3) EMI www.active-semi.com
Emitter Switching Topology 1) Slow turn-off 2) VCEO blocking rating (450V for MJE13003) 1) Fast turn-off 2) VCBO blocking rating (700V for MJE13003) www.active-semi.com
EST Advantages • 1) Fast turn-off time • 2) VCBO blocking voltage rating • 3) Low High Frequency EMI No Y-cap www.active-semi.com
