Differences between CoolSET TM F3 & F3R ICE3BR4765J 1 Technology ICE3B0565 Bipolar ICE3B0565J BiCMOS ICE3BR4765J BiCMOS Benefits for F3R BiCMOS technology can provide wider Vcc voltage ( 27V max ) 1 Frequency ( KHz ) 67 67 65 2 Soft start defined by C SOFTS built-in 20ms built-in 20ms 3 Blanking time defined by C Spliting the soft start, blanking time and SOFTS ( basic ) frequency jitter period can make those individual features peformed more effective. Extendable blanking 4 N.A. defined by C time BK (ICE3B0565J has one capacitor to control all 3 features) defined by 5 Freq. jitter period N.A. built-in ( 4ms ) C SOFTS 6 Modulated gate drive Yes N.A. Yes 1. It can help to improve the radiated EMI more effectively. 2. It can reduce the spikes at the output rectifier so that snubber circuit can be eliminated. 7 External protection enable pin N.A. auto-restart ( pin 1 < 0.3V ) It can provide extra customer defined protection fucntion. 8 Vcc OVP ( additional ) N.A. >25.5V The new Vcc OVP feature can protect the Vcc pin more effectively. 9 Over load trigger level ( C4 ) 4.8V 4.5V 4.0V Lower over load trigger voltage can have faster protection response. 10 Burst level (C6b,C6a) 3.4V / 4.0V 3.0V /3.61V 3.0V / 3.5V Lower the burst on trigger level can lower the output ripple voltage during burst mode. 11 Gate driving capability P o = 30W P o = 20W P o = 30W Series can be expanded to 30W ( same as F3 CoolSET ) Page 19
