Overview
The LV52204MU is a high voltage boost driver for LED drive. LED current is set by the external resistor R1 and LED
dimming can be done by changing FB voltage with PWM or 1-Wire.
Features
• Operating Voltage from 2.7V to 5.5V
• Integrated 40V MOSFET
• 1-Wire 32 level digital and PWM dimming
• 600kHz Switching Frequency
Typical Applications
• LED Display Backlight Control
