AC/DC Drivers

PWM Control IC

BM1P065FJ

● General

The PWM control IC for AC/DC “BM1P065FJ”

provides an optimum system for all products that

include an electrical outlet.

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.

A

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.
