Typical Application Circuit
Features
High efficiency (>76% at universal input)
Low standby mode power consumption (<1W at 230Vac input and 0.5W load)
Low component count
Enhanced system reliability through various protection functions
Low EMI through frequency modulation
Internal soft-start (15ms)
Key Design Notes
The delay time for over load protection is designed to be about 30ms with C106 of 47nF. If faster/slower triggering of OLP
is required, C106 can be changed to a smaller/larger value(eg. 100nF for about 60ms).
Using a resistor R104(3.3
) on Ipk pin (#4), the pule-by-pulse peak current limit level(I
LIM
) is adjusted to about 0.8A.
The branch formed by D103, C108 and R106 provides another I
LIM
adjustment having a negative slope to the input
voltage. The I
LIM
value decreases as the input voltage level increases.
