TYPICAL APPLICATIONS
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.
