SAN JOSE, Calif. -- January 14, 2013

As today’s consumer electronics and home appliances become more sophisticated,
they require better performance and reliability. Designers of these types of
switch mode power supply (SMPS) systems need space-saving, cost-effective
power supply solutions with high energy efficiency that meet strict energy
regulations. Fairchild Semiconductor’s (NYSE: FCS) FSL1x series of FPS™ Green
Mode Power Switches help designers address these challenges.

The highly integrated FSL1x series is a two-chip-one-package design with an
avalanche-rugged 650-800V SenseFET and a current-mode pulse width modulator
(PWM) that is specifically designed to reduce component count and system costs
for offline SMPS. Additionally, the green-mode functionality of the PWM
controller helps to meet global energy regulations by minimizing standby power

These power switches allow for a longer survival at breakdown mode due to
Fairchild’s vertical DMOS technology with rugged avalanche characteristics,
making them superior to the competitor’s designs that utilize lateral DMOS
technology. For maximum design flexibility, system productivity and
reliability, the FPS family allows for single platform design for various
input voltage requirements, so that both domestic and export models can meet
all standard passive component requirements.

Compared to other discrete MOSFET and PWM controller solutions, the FSL1x
series provides a basic platform ideally suited for significantly reducing
total system costs and component count without sacrificing efficiency,
productivity and system reliability.

Features and Benefits:

  *Frequency modulation for attenuating electromagnetic interference (EMI)
  *Internal soft-start circuit smoothly increases output voltage to help
    prevent transformer saturation while reducing stress on the secondary
  *Burst-mode operation to minimize power dissipation in standby mode
  *Integrated protection features reduce the need for external components,
    protections include: overload protection (OLP), over-voltage protection
    (OVP), thermal shutdown (TSD), abnormal over-current protection (AOCP),
    output short protection (OSP) and auto restart mode
