Description
STEVAL-ISA170V1 is a 150 W converter tailored
to a typical specification for an all-in-one (AIO)
computer power supply or a high power adapter.
The architecture is based on a two-stage
approach: a front-end PFC pre-regulator based
on the L6563H TM PFC controller and a
downstream LLC resonant half-bridge converter
using the L6699 resonant controller.
The L6699 integrates some very innovative
functions such as self-adjusting adaptive dead-
time, anti-capacitive mode protection and a
proprietary “safe-start” procedure that prevents
hard switching at startup. The innovative adaptive
synchronous rectification controller SRK2001
allows maximum efficiency in all load conditions.
Thanks to the chipset used, the main feature of
this power supply is its very high efficiency, which
is compliant with ENERGY STAR^® eligibility
criteria for adapters and computers. The power
supply also has very good efficiency at light load,
and compliance with EuP Lot 6 Tier 2
requirements. No load input power consumption
is very low as well, and within the international
regulation limits.
