Description
SL6802 is a triple DC-DC converter designed to drive AMOLED display panel requiring 3 supply rails. It integrates an 200mA step-up converter VPOS, an 200mA inverting converter VNEG and an 20mA auxiliary LDO AVDD. 

The device is particularly suitable for battery operated products, in which the major concern is the overall system efficiency. The digital control allows programming the VNEG in digital steps. 

Excellent line and load regulation, soft start with controlled inrush current limit, thermal shutdown and short circuit protection are also integrated.
