Description
The WD3124DA 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 WD3124DA 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.
The WD3124DA also features a very low shutdown
current, an automatic soft-start mode to limit inrush
current, as well as over current, over voltage and
over-Thermal shutdown control.
A low current sense reference voltage (50mV) allows
the use of small 0603 current sensing resistors.
The WD3124DA is available in Green DFN3×3-10L
package and is specified over an ambient temperature
range of -40to +85.
