概述

The R1293 Series are multi power supply ICs dedicated for mid-size TFT LCD panels. Each of the IC consists of a PWM control step-up DC/DC converter, an LDO regulator, a VCOM amplifier and six GAMMA amplifiers. The output noise can be reduced by SEL pin. (SEL pin "H": normal mode, SEL pin "L": low noise mode.) The MOSFET for step-up DC/DC converter is built-in and, low power operation is realized by standby mode. The package is 4mm square DFN(PLP)0404-32.
