INFORMATION
IR3M30M/U
3-output DC-DC Converter for small/medium TFT-LCD panels
Under development
Outline
IR3M30M/U are DC-DC converters for small/medium TFT-LCD panels. These models make it possible to create a
power supply system with a single chip, by offering three types of output voltages (-10 V, +5 V, +15 V) from a single
www.DataSheet4U+.c3omV operation, unlike a conventional system requiring multiple chips. In addition, the mounting area can be decreased
due to its small 32 VQFN package (5 mm x 5 mm).
Main Specifications
