The SGM38049 is designed for powering AMOLED displays which requires VELVDD, VELVSS and VAVDD. The device integrates a positive Buck-Boost converter with Single Inductor Dual Output (SIDO) topology for ELVDD and AVDD, and one inverting Buck-Boost converter for ELVSS.
The SGM38049 generates two positive and one negative precision regulated voltage power sources AVDD, ELVDD and ELVSS. The positive output ELVDD is programmable from 2.6V to 5V with 100mV per step, and the negative output ELVSS is programmable from -0.3V to -9.2V with 100mV per step. The combined ELVDD and ELVSS output capability is up to 250mA. The AVDD is programmable from 2.7V to 3.6V with 100mV per step and 30mA output capability.
The SGM38049 is available in a Green WLCSP- 1.72×2.2-20B package. It operates over an ambient temperature range of -40℃ to +85℃.
