LW32A23W/LW40A23W
Operation of W6853
Outlines
1. MBS : Multi bottom skip (medium load area)
The circuit has the PWM reference time T=14uS, 70 kHz internally and is designed to turn on at a bottom
less than 14uS.
Note : MBS operations should not be counted in the overload, overcurrent area. (Bottom is not extended)
If the overload condition continues, OLP will be triggered to shut down the operation. Normally ,it
is not counted during startup, and if the down edge is detected only once after a count of 2, it is
considered abnormal and the oscillation is stopped.
Sub circuit
MIC internal reference time
On at a Bottom after the Reference Time that starts with ON.
On with the Bottom Count same as memorizing circuit.
