Typical Application Circuit of FSQ0365RN
Features
Key Design Notes
1. Schematic
High efficiency ( >77% at universal input)
Low standby mode power consumption (<1W at 230V
Reduce EMI noise through Valley Switching operation
Enhanced system reliability through various protection functions
Internal soft-start (15ms)
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
voltage can be adjusted.
The SMD-type 100nF capacitor must be placed as close as possible to V
sating noises and to improved surge immunity.
