Description
In general, a Quasi-Resonant Converter (QRC) shows lower
EMI and higher power conversion efficiency compared to
conventional hard-switched converter with a fixed switching
frequency. Therefore,
a
QRC is well suited for noise-
sensitive applications, such as color TV and audio. Each
product in the FSCQ-Series contains an integrated Pulse
Width Modulation (PWM) controller and
a
SenseFET, and
is
specifically designed for quasi-resonant off-line Switch
Mode Power Supplies (SMPS) with minimal external
components. The PWM controller includes an integrated fixed
frequency oscillator, under voltage lockout, leading edge
blanking (LEB), optimized gate driver, internal soft start,
temperature-compensated precise current sources for a loop
compensation
,
and self protection circuitry. Compared with
a
discrete MOSFET and PWM controller solution, the FSCQ-
Series can reduce total cost, component count, size
,
and weight,
while simultaneously increasing efficiency, productivity, and
system reliability.
These devices
provide a basic platform
that is well suited for cost-effective designs of quasi-resonant
switching flyback converters.
