SGM38042A
Single Inductor Triple Output AMOLED Display Power Supply
Charge Pump Mode Power Supply for Wearable AMOLED Products
The SGM38042A generates 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. 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 100mA in boost-inverter mode and also works in buck-inverter mode.
The SGM38042A is available in a Green WLCSP-1.51×2.10-15B package. It operates over an ambient temperature range of -40℃ to +85℃.
