General Description
The RY3750 is a high-frequency boost converter dedicated for small to medium LCD bias supply. The device is
ideal to generate output voltages up to 30V from a dual-cell NiMH/NiCd or a single-cell Li-Ion battery. The part
can also be used to generate standard 3.3V or 5V to 12V power conversions. Optimized operation frequency can
meet the requirement of small LC filters value and low operation current with high efficiency. Internal soft start
function can reduce the inrush current. The device has a 0.6A switch current limit, offering lower output voltage
ripple and allows the use of a smaller form factor inductor for lower power applications. Low quiescent current
allows device operation at very high efficiencies over the entire load current range. The RY3750 is available in
SOT23-5 package.
