ZXSC400 - LED DRIVER BOOST CONVERTER

Datasheet Summary

Description

The ZXSC400 is a voltage mode boost converter in the SOT23-6 package.

Its low feedback voltage allows the current in a chain of LEDs to be set and accurately monitored with a single resistor giving minimal losses.

Features

1.8V to 8V supply range.
Typical output regulation of Ϯ1%.
Over 80% typical efficiency.
4.5␮A typical shutdown current.
Series connection for ultimate LED current matching SOT23-6.

ZXSC400 LED DRIVER BOOST CONVERTER DESCRIPTION The ZXSC400 is a voltage mode boost converter in the SOT23-6 package. Its low feedback voltage allows the current in a chain of LEDs to be set and accurately monitored with a single resistor giving minimal losses. Its excellent load and line regulation means that for the full supply range from lithium-ion cells, the LED current will typically change by less than 1%. Using high efficiency Zetex switching transistors with ratings of 20V and higher allow many LEDs to be chained in series for the best LED current matching possible. FEATURES • 1.8V to 8V supply range • Typical output regulation of Ϯ1% • Over 80% typical efficiency • 4.
