ZXLD383 Datasheet, Diodes Incorporated

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 techniq.

requiring step-up voltage conversion from a very low input voltage. The IC generates constant current pulses that are id.
