Description
The highly integrated FSBH-series consists of an
integrated current-mode Pulse Width Modulator (PWM)
and an avalanche-rugged 700 V SenseFET. It is
specifically designed for high-performance offline
Switched-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 18 kHz. 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 VFB is lower than 1.6 V, which
allows an operating current of only 2.5 mA.
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 90 VAC to 264 VAC.
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 VDD drops below the VTH-OLP, then the
controller starts up again. As long as VDD exceeds 28 V,
the internal OVP circuit is triggered.
Compared with a discrete MOSFET and controller or
RCC switching converter solution, the FSBH-series
reduces 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.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
