PWM Control IC
BM1P066FJ
â General
The PWM control IC for AC/DC âBM1P066FJâ
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.
