AL17150-10B
HIGH VOLTAGE STEP-DOWN SWITCHER UP TO 300mA OUTPUT CURRENT
Description
Pin Assignments
NEW PRODUCT
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 optocoupler 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.

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.

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.
The AL17150-10B has rich protection features to enhance the system
safety and reliability. It has Over Temperature Protection, V CC Under
Voltage Lock function, Output Short Protection, Over Load Protection
and Open Loop Protection.
