SINGLE OR MULTI CELL LED DRIVER SOLUTION
Summary
The ZXLD383 is a single or multi cell LED driver designed for applications requiring step-up voltage conversion from a very
low input voltage. The IC generates constant current pulses that are ideal for driving single or multiple LEDs over a wide
range of operating voltages. It includes an on/off enable input that can be driven directly from a photocell array or an open
collector/drain logic output. The enable input features an ultra-low voltage drop diode to ground, eliminating the need for a
photocell array isolation diode in Garden Light applications.
The ZXLD383 uses a PFM control technique to drive an internal switching transistor which exhibits a low saturation
resistance. This ensures high efficiency, even for input voltages as low as 1.0V.
The IC can start up under full load and operates down to an input voltage of below 0.9V.
The ZXLD383 is offered in the space saving TSOT23-5 package or in die form, offering an excellent cost vs. performance
solution for single cell LED driving applications.
