LV52204MU: LED Boost Driver with PWM and 1-Wire Dimming
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
| Benefits- Wide operating input voltage range for hand held equipment
- White LED can do series connection till 10 pcs
- The LED's current can do 32 phases adjustment
- Small inductor is available
|
Applications- LED Display Backlight Control
