AL17050

UNIVERSAL HIGH VOLTAGE STEP DOWN CONVERTER

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.

DRAIN

V_CC

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.

SOURCE

SOT25

The AL17050 has rich protection features to enhance the system

safety and reliability. It has Over Temperature Protection, V_CCUnder

Voltage Lock function, Output Short Protection, Over Load Protection

and Open Loop Protection.
