The SGM38042 generates both positive and negative precision regulated voltage power sources with a control scheme for single inductor dual output converter. Outputs are programmable in 100mV steps in 2.4V to 6.4V range, which are commonly used in drivers for LCD displays and AMOLED displays, as well as in any other circuits requiring both rails. A linear regulator capable of 50mA output current is also integrated. The device is equipped with 1-Wire interface. With input in the range of 2.7V to 5.5V, the device is optimized for loading 40mA in boost-inverter mode and also works in buck-inverter mode.

The SGM38042 is available in Green WLCSP- 1.51×2.10-15B package. It operates over an ambient temperature range of -40℃ to +85℃.
