Description

The MAX17065 provides the power-supply rails for active-matrix, organic light-emitting diode (OLED) displays.

The MAX17065 includes a step-up DC-DC converter, an inverting DC-DC converter, a regulated positive charge pump, a regulated negative charge pump, and a low-dropout linear regulator (LDO). Synchronous rectifiers are integrated into the IC, eliminating the need for external power components. An I²C interface is used to program the switching frequency, the operating mode, and the cycle-by-cycle current limit of the noninverting and step-up converters, as well as the output voltages of the inverting converter and the charge pumps. Efficiency of 94% can be achieved for the step-up and 83% for the inverting converter.

The MAX17065 is packaged into a space-efficient 28-pin, 4mm x 4mm TQFN package with an exposed backside pad (EP) to enhance thermal characteristics.
