BM1Q011FJ
●General Description
The quasi-resonant controller typed AC/DC converter IC
BM1Q011FJ 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.
This IC built in HV starter circuit, it contributes to low
consumption power and high speed start.
Because the burst mode is built-in and IC consumption
current is low, stand-by power becomes very low.
Because BM1Q011FJ 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, BM1Q011FJ are highly safety.
