ZXSC300E5TA Description

Short technical summary and product information.

The ZXSC300E5TA is a PFM controller IC from Diodes Incorporated, designed for step-up voltage conversion from very low input voltages, typically from single 1.5V or 1.2V battery cells. This IC generates constant current pulses ideal for driving single or multiple LEDs over a wide range of operating voltages.

 

Key features include a minimum operating input voltage of 0.8V and up to 94% efficiency. The ZXSC300E5TA drives an external switching transistor, enabling high efficiency conversion even with input voltages below 1 volt. It is offered in a compact SOT-23-5 package, providing a high efficiency, small-size circuit solution when combined with a SOT23 switching transistor.

 

This LED driver is well-suited for applications such as LED flashlights, torches, LED backlights, and general white or multiple LED driving. The circuit can start up under full load and operates down to an input voltage of 0.8 volts, ensuring reliable performance in various conditions.
