The SGM3837A is designed for powering AMOLED (Active Matrix Organic LED) displays which require VELVDD, VELVSS and VAVDD. The device integrates two Boost converters, VO1 for VELVDD and VO3 for VAVDD, and one inverting Buck-Boost converter VO2 for VELVSS. Output voltages of all the three converters can be programmed in digital steps through the digital interface control pins (ASWIRE & ESWIRE).
The SGM3837A is available in a Green WLCSP-2×2- 25B-A package.
