PA5910

Switching Type LED Driver

ANALOG PRODUCTS DIVISION

Description

Features

The PA5910 is a high efficiency LED driver control

Integrated Circuit.

•

Constant current LED driver:

20mA to 2A programmable

Step-up or step-down operation

>90 efficiency

It is a universal control LED driver that can be

configured to operate as a step-up or step-down

LED driver.

2.5V to 450V

Up to 2MHz switching frequency

The input and output voltage can be extended

beyond 450V.

Applications

The PA5910 uses a fixed off time and 2MHz

switching frequency can be achieved.
