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.

●Description of Blocks
( 1-1 ) Starter Circuit VH pin(8pin)
IC builds in starter circuit (tolerates 650V) to VH pin (8pin). It enables to be low standby power and high speed starting.
The operating current is shown in Fig-6.After starting IC, consumption power is decided by multiplied idling current ISTART3
(typ=10uA) with VH voltage. The loss by the idling current is below.
ex) power consumption of starter circuit only
Vac=100V Power=100V*√2*10uA=1.41mW
Vac=240V Power=240V*√2*10uA=3.38mW
Start time is decided by VH current and VCC pin capacitor.
The reference value of start time is shown in Fig7. For example, VCC capacitor is charged within 0.1s in CVCC=10uF
When VCC pin is shorted to GND, current of “ISTART1” flows. (Fig-6)
When VH pin is shorted to GND, large current flows from VH line to GND. To prevent it, need to insert
resistor (5kΩ~60kΩ) of “RVH” to limit current between VH line and VH pin.
When VH pin is shorted to GND, the power of VH2/RVH is applied. For that, please decide resistor size to confirm power
dissipation. When it does not satisfy power dissipation by one resistor, please use more than two resistors.
