LM2758TLEV
The LM2758 Evaluation board is for the LM2758, 700mA flash LED driver.
LM2758TLEV
Overview
The LM2758 is an integrated low-noise, high-current switched capacitor DC/DC converter with a regulated current source. The device is capable of driving loads up to 700mA from a single-cell Li-Ion battery. Maximum efficiency is achieved over the input voltage range by actively selecting the proper gain based on the LED forward voltage and current requirements
Features
- Up to 700mA Output Current
- Ultra-Small Solution Size
-No Inductor, Only 4 Capacitors Required
-1.514 mm x 1.996 mm x 0.6 mm thin micro SMD package - 90% Peak Efficiency
- Indicator, Torch, and Flash Modes
- Time-Out Circuitry Limits Flash duration to 814 msec. (typ.)
- Adaptive 1x and 1.5x Gains for Maximum Efficiency
- True Shutdown
- Internal Soft-Start eliminates Inrush Current
- The LM2758 is offered in National?s tiny 12-bump thin micro SMD package
Applications:
- Camera Flash in Mobile Phones
- Flash for Digital Cameras
- Keypad LED Drive
- Audio amplifier power supply
- Low-current Camera Flash
