HIGH VOLTAGE STEP-DOWN SWITCHER UP TO 300mA OUTPUT CURRENT

Description

Pin Assignments

The AL17150-10B is a universal high voltage input step-down

regulator product family, which 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 connected LED lighting power

supply for micro-controllers and other IoT applications.

Drain

The AL17150-10B integrates a 500V/1A MOSFET that can make it

use fewer external components and create a low Bill Of Material

(BOM) cost solution. The AL17150-10B can provide up to 300mA

output current and lower than 50mW standby power, which is very

suitable for IoT connected lighting devices.

VCC

The AL17150-10B achieves excellent regulation and high power

efficiency. The characteristics of max peak current and driving

frequency vary as the load change, which can get excellent efficiency

performance at light load and improve the overall average efficiency.

SO-7

Applications

The AL17150-10B 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.
