AL17050
UNIVERSAL HIGH VOLTAGE STEP DOWN CONVERTER ADVANCED INFORMATION Description Pin Assignments The AL17050 is a universal AC high voltage input step down regulator
that provides accurate constant voltage (CV) and outstanding
dynamic performance without requiring an opto-coupler over line and
Load regulation. Typical applications are offline low power
applications including home appliance applications and IoT
applications. (Top View) Working with a single winding inductor and integrating a 500V
MOSFET internal can make it use fewer external components and
create a low Bill Of Material (BOM) cost solution.
The AL17050 achieves excellent regulation and high power efficiency.
The characteristics of max peak current and driving frequency vary as
the load change can get excellent efficiency performance at light load
and improve the overall average efficiency.
The AL17050 has rich protection features to enhance the system
safety and reliability. It has Over Temperature Protection, VCC Under
Voltage Lock function, Output Short Protection, Over Load Protection
and Open Loop Protection.
