NEW PRODUCT INFORMATION IR3M30M/U ＜Outline＞ 3-output DC-DC Converter for small/medium TFT-LCD panels Under development 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 .. +3 V 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＞ - PWM switching system - Step-up type/Step-down type/Inverting type selectable (CH2) - Built-in switching transistor (CH1/CH2) - Selectable from output ON/OFF sequence - Supply voltage: 2.7 to 5.5 V - Supply current: 3 m A (TYP.) - Maximum duty: 80% (Step-up circuit) 100% (Step-down circuit) - Internal oscillation frequency: 70 k Hz to 1.0 MHz - Reference voltage precision: ±1.5% - Operating temperature: -40 to 85℃ - Package: 32QFP(P-QFP032-0707) 32VQFN(P-VQFN032-0505) ＜System Configuration Example＞ 3 V (2.7 to 5.5 V） ★IR3M30M/U Power supply IC +15 V -10 V Gate driver Control logic +5 V TFT-LCD (Digital signal input) Gray-scale IC D A C Control logic Controller Source driver Contact SHARP in order to obtain the latest device specification sheets before using any SHARP device.
