The SGM3833A and SGM3833B are designed to drive AMOLED displays (Active Matrix Organic Light Emitting Diode) requiring VAVDD, VELVDD and VELVSS. The devices integrate a boost converter for VELVDD, an inverting buck-boost converter for VELVSS and a boost converter for VAVDD, which are suitable for battery operated products. The digital interface control pin (CTRL) allows programming VAVDD, VELVDD and VELVSS in digital steps.
The SGM3833A and SGM3833B are both available in Green TQFN-3×3-16L packages. They operate over an ambient temperature range of -40℃ to +85℃.
