LED lighting drivers from Diodes Incorporated simplify low power single cell applications
The ZXLD381 and ZXLD383 LED drivers from Diodes Incorporated have been designed to provide the simplest possible solution for driving low power high brightness LEDs from a single solar or rechargeable battery cell. PFM DC-DC converters with an on-board low saturation voltage switching transistor, the devices only need an inductor for high efficiency LED illumination.Oper
The ZXLD383 combines the features of the ZXLD381 with a dual function enable input which provides an inhibit control and an ultra-low voltage drop isolation diode for battery charging purposes in garden lights. This eliminates the need for an external photocell array isolation diode, making the driver ideal for solar powered garden and walkway lamps.
