Features
! 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 AC input and 0.5W load)
! Reduce EMI noise through valley switching operation
! Enhanced system reliability through various protection functions
! Internal soft-start (17.5ms)
Key Design Notes
! 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 Sync must be between 4.7V and 8V just after MOSFET turn-off to guarantee hybrid control and
to avoid OVP triggering during normal operation.
! 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 improve surge immunity.
