LM3519 - High Frequency Boost White LED Driver

LM3519 Description

LM3519 High Frequency Boost White LED Driver with High-Speed PWM Brightness Control September 2005 LM3519 High Frequency Boost White LED Driver with.
The LM3519 drives up to 4 white LEDs with constant current to provide LCD backlighting in handheld devices.

LM3519 Features

* a proprietary PFM regulation architecture with switching frequencies between 2MHz to 8MHz, minimizing inductor size. Over-voltage protection circuitry and high frequency operation permit the use of low-cost small output capacitors. During shutdown, the output is disconnected from the input in order

LM3519 Applications

* n LCD, White LED Backlighting on Mobile Phones n Digital Still Cameras and PDAs n General Purpose LED Lighting in Handheld Devices Typical Application 20160201 FIGURE 1. Typical Application Circuit © 2005 National Semiconductor Corporation DS201602 www. national. com LM3519 Connection Diagram
