Overview
SGM3141B 700mA Buck/Boost Charge Pump LED Driver GENERAL DESCRIPTION The SGM3141B is a current-regulated charge pump ideal for powering high brightness LEDs for camera flash applications.
The charge pump can be set to regulate two current levels for Flash and Torch modes.
The SGM3141B automatically switches modes between step-up and step-down ensuring that LED current does not depend on the forward voltage.
It switches at 2.
2MHz, allowing the use of tiny components.
The supply voltage ranges from 2.
7V to 5.
5V and is ideally suited for all applications powered by a single Li-ion battery cell or three to four NiCd, NiMH, or Alkaline battery cells.
FEATURES ● Output Current Up to 700mA ● Up to 90% Efficiency in Torch Mode ● Adjustable Flash Mode Current ● 1× and 2× Automatic Modes for High Efficiency ● Input Voltage Range: 2.
7V to 5.
5V ● Minimum External Components: No Inductors ● High Frequency Operation: 2.
2MHz ● Low 47mV Reference for Low Loss Sensing ● IQ < 1μA in Shutdown ● Built-I...
