AC/DC Drivers
Quasi-Resonant Control type
DC/DC Converter IC
BM1Q00XFJ Series
●General
Description
The quasi-resonant controller typed AC/DC converter IC
(BM1Q00XFJ series) provides an optimum system for all
products that include an electrical outlet.
Quasi-resonant operation enables soft switching and helps
to keep EMI low.
With MOSFET for switching and current detection resistors
as external devices, a higher degree of design freedom is
achieved.
As BM1Q00XFJ series built in HV starter circuit, it
contributes to low consumption power and high speed start.
Because the built-in burst mode is reduced switching loss
and IC consumption current is low, Stand-by power is very
low.
Because BM1Q00XFJ series built-in soft-start, burst mode,
over current limiter which is cycle-by-cycle, over load
protection, over voltage protection, CS open protection and
so on, BM1Q00XFJ series are highly safety.
