16 / 24 page  © 2006 Fairchild Semiconductor Corporation www.fairchildsemi.com FSQ0365, FSQ0265, FSQ0165, FSQ321, FSQ311 Rev. 1.0.4 16 Typical Application Circuit of FSQ0365RN Features High efficiency ( >77% at universal input) Low standby mode power consumption (<1W at 230VAC 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 Vsync 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 VCC pin to avoid malfunction by abrupt pul- sating noises and to improved surge immunity. 1. Schematic Figure 29.
