TCS3454
High Performance,30V Output,1.2MHz Bias Driver
产品描述
The 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 1.4A 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 available in SOT23-5 package.
