PWM Control IC

BM1P105FJ

● General

● Features

The PWM control IC for AC/DC “BM1P105FJ”

provides an optimum system for all products that

include an electrical outlet.

 PWM frequency: 100 kHz

 PWM current mode method

 Frequency hopping function

A built-in start circuit that withstands 650 V helps to

keep power consumption low. Both isolated and

non-isolated versions are supported, making for

simpler design of various types of low-power

converters. Switching MOSFET and current detection

resistors are external devices, thus achieving a higher

degree of freedom in power supply design. The

switching frequency is set as fixed. Since current mode

control is used, a current limit is imposed in each cycle,

and excellent performance is demonstrated in

bandwidth and transient response. With a light load,

frequency is reduced and higher efficiency is realized.

 Burst operation during light load / Frequency

reduction function

 650 V start circuit

 VCC pin undervoltage protection

 VCC pin overvoltage protection

 CS pin open protection

 CS pin Leading-Edge-Blanking function

 Per-cycle overcurrent limiter function

 Overcurrent limiter with AC voltage compensation

function

 Soft start function

 Secondary overcurrent protection circuit

frequency hopping function is also built in,

contributing to low EMI.

Also on chip are soft start and burst functions, a

per-cycle overcurrent limiter, VCC overvoltage

protection, overload protection, and other protection

functions.
