F
Typical Application Circuit
Features
High efficiency (> 78% at 115 Vac and 230 Vac input)
Low standby mode power consumption (< 0.8W at
230 Vac input and 0.5W load)
Enhanced system reliability through various protection
functions
Low EMI through frequency modulation
Internal soft-start (10ms)
Line UVLO function can be achieved using external
component
Key Design Notes
The delay time for overload protection is designed to
be about 30ms with C8 of 47nF. If faster/slower trig-
gering of OLP is required, C8 can be changed to a
smaller/larger value (e.g. 100nF for about 60ms).
ZP1, DL1, RL1, RL2, RL3, RL4, RL5, RL7, QL1, QL2,
and CL9 build a Line Under Voltage Lock Out block
(UVLO). The zener voltage of ZP1 determines the
input voltage which makes FPS turn on. RL5 and DL1
provide a reference voltage from V
CC
. If the input volt-
age divided by RL1, RL2, and RL4 is lower than the
zener voltage of DL1, QL1 and QL2 turn on and pull
down Vfb to ground.
This evaluation board and corresponding test report
can be provided.
