SGM38042B-5

Active

Single Inductor Triple Output AMOLED Display Power Supply

The SGM38042B-1, SGM38042B-3 and SGM38042B-5 generate both positive and negative precision regulated voltage power sources with a control scheme for single inductor dual output converter. The positive output is programmable from 2.4V to 6.4V with 100mV per step, and the negative output is programmable from -2V to -3.2V with 50mV per step.

A linear regulator capable of 50mA output current is also integrated. These devices are equipped with 1-Wire interface. With input in the range of 2.7V to 5.5V, these devices are optimized for loading 100mA in boost-inverter mode and also work in buck-inverter mode.

The SGM38042B-1/3/5 are available in a Green WLCSP-1.51×2.10-15B package. They operate over an ambient temperature range of -40℃ to +85℃.
