DESCRIPTION

The ML0308 are high efficiency, white LED

driver and step-up DC/DC converters in a tiny

SOT23 5-lead package. The ML0308 switches

at 1.2MHz. High switching frequency permits

the use of tiny, low profile inductors and

capacitor to minimize footprint and cost in

space-conscious portable applications.

The 18V switch allows high output voltage up

to 16V to be easily generated in a simple boost

topology

avoiding

the

use

of

costly

transformers.
