1. Schematic
Average efficiency of 25%, 50%, 75%, and 100% load conditions is higher than 80% 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 (17.5ms)
The delay time for overload protection is designed to be about 23ms with C105 of 33nF. If faster/slower triggering of
OLP is required, C105 can be changed to a smaller/larger value (e.g. 100nF for 70ms).
The input voltage of V
to avoid OVP triggering during normal operation.
The SMD-type 100nF capacitor must be placed as close as possible to V
sating noises and to improve surge immunity.
