Diodes Incorporated ZXLD383 LED Drivers

Diodes Incorporated ZXLD383 LED Drivers are designed for applications requiring step-up voltage conversion from a very low input voltage. The ZXLD383 LED driver IC generates constant current pulses that are ideal for driving single or multiple LEDs over a wide range of operating voltages. This Diodes Incorporated Boost and Buck-boost LED driver provides 85% efficiency and increased battery life.

The Diodes Incorporated ZXLD383 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.
