LM2758 - Switched Capacitor Flash LED Driver

General Description

The LM2758 device is an integrated low-noise, highcurrent switched capacitor DC-DC converter with a regulated current sink.

The device is capable of driving loads up to 700 mA from a single-cell Li-Ion battery.

Key Features

  • 1 Up to 700-mA Output Current.
  • 90% Peak Efficiency.
  • Indicator, Torch, and Flash Modes.
  • Time-Out Circuitry Limits Flash Duration to 814 Milliseconds (Typical).
  • Adaptive 1× and 1.5× Gains for Maximum Efficiency.
  • True Shutdown.
  • Internal Soft-Start Eliminates Inrush Current.
  • Ultra-Small Solution Size.
  • No Inductor, Only 4 Capacitors and a Resistor Required.
  • 2.022 mm × 1.527 mm × 0.6 mm Thin DSBGA package 2 Appli.
