High efficiency ( >77% at universal input)
Low standby mode power consumption (<1W at 230V AC input and 0.5W load)
Reduce EMI noise through Valley Switching operation
Enhanced system reliability through various protection functions
Internal soft-start: 15ms
Key Design Notes
? The delay time for overload protection is designed to be about 30ms with C107 of 47nF. If faster/slower triggering
of OLP is required, C107 can be changed to a smaller/larger value (eg. 100nF for 60ms).
? The input voltage of V sync must be higher than -0.3V. By proper voltage sharing by R106 & R107 resistors, the input
voltage can be adjusted.
? The SMD-type 100nF capacitor must be placed as close as possible to V CC pin to avoid malfunction by abrupt
pulsating noises and to improved surge immunity .
