PWM Control type
DC/DC converter IC
BM1P061FJ / BM1P062FJ / BM1P101FJ / BM1P102FJ
●General
The PWM type DC/DC converter (BM1Pxxx) for
●Features
PWM frequency : 65kHz, 100kHz
AC/DC provide an optimum system for all products
that include an electrical outlet.
BM1Pxxx supports both isolated and non-isolated
devices, enabling simpler design of various types of
low-power electrical converters.
PWM current mode method
Frequency Hopping function
Burst operation / Frequency reduction function
when load is light
Built-in 650V start circuit
BM1Pxxx built in a HV starter circuit that tolerates
650V, it contributes to low-power consumption.
With switching MOSFET and current detection
resistors as external devices, a higher degree of
design freedom is achieved. Since current mode
control is utilized, current is restricted in each cycle
and excellent performance is demonstrated in
bandwidth and transient response.
VCC pin under voltage protection
VCC pin over voltage protection
CS pin Open protection
CS pin Leading-Edge-Blanking function
Per-cycle over current protection circuit
Current protection with AC voltage compensation
Soft start
Secondary Over current protection circuit
At light load, the switching frequency is reduced and
high efficiency is achieved.
A frequency hopping function is also on chip, which
contributes to low EMI.
BM1Pxxx has rich protection.
