Description
The highly integrated FSL137H 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. The
green-mode function enables the power supply to meet
international power conservation requirements. With the
internal high-voltage startup circuitry, the power loss
due to bleeding resistors is also eliminated. To further
reduce power consumption, the PWM controller is
manufactured using the BiCMOS process, which allows
an operating current of only 3.5mA.
The FSL137H built-in synchronized slope compensation
achieves 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 FSL137H 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-circuit failure occurs. PWM
output is disabled until V DD drops below the UVLO lower
limit, when the controller starts up again. As long as V DD
exceeds ~28V, the internal OVP circuit is triggered.
Compared to a discrete MOSFET and controller or RCC
switching converter solution, the FSL137H reduces total
component count, design size, and weight while
increasing efficiency, productivity, and system reliability.
These devices provide a basic platform well suited for
design of cost-effective flyback converters.
