The MAX17065 is packaged into a 28-pin, 4mm x 4mm TQFN package with an exposed backside pad (EP) to enhance thermal characteristics. The MAX17065 provides the power-supply rails for active-matrix, OLED (organic light-emitting diode) displays.

The MAX17065 includes:

• an inverting DC-DC converter
• a step-up DC-DC converter
• a regulated negative charge pump
• a regulated positive charge pump
• 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.

Applications
