Description
The highly integrated FSBH-series consists of an
integrated current-mode Pulse Width Modulator (PWM)
and an avalanche-rugged 700V SenseFET. It is
specifically designed for high-performance offline
Switch Mode Power Supplies (SMPS) with minimal
external components.
The integrated PWM controller features include a
proprietary green-mode function that provides off-time
modulation to linearly decrease the switching frequency
at light-load conditions to minimize standby power
consumption. To avoid acoustic-noise problems, the
minimum PWM frequency is set above 18kHz. This
green-mode function enables the power supply to meet
international power conservation requirements. The
PWM controller is manufactured using the BiCMOS
process to further reduce power consumption. The
FSBH-series turns off some internal circuits to improve
power saving when V FB is lower than 1.6V, which allows
an operating current of only 2.5mA.
The FSBH-series has built-in synchronized slope
compensation to achieve stable peak-current-mode
control. The proprietary external line compensation
ensures constant output power limit over a wide AC
input voltage range, from 90V AC to 264V AC .
The FSBH-series provides many protection functions. In
addition to cycle-by-cycle current limiting, the internal
open-loop protection circuit ensures safety when an
open-loop or output short occurs. PWM output is
disabled until V DD drops below the V TH-OLP , then the
controller starts up again. As long as V DD exceeds 28V,
the internal OVP circuit is triggered.
Compared with a discrete MOSFET and controller or
RCC switching converter solution, the FSBH-series
reduces total component count, design size, and
weight; while increasing efficiency, productivity, and
system reliability. These devices provide a basic
platform that is well suited for the design of cost-
effective flyback converters, such as in PC auxiliary
power supplies.
