RT4723P

Dual Output AMOLED Bias

General Description

Features

 2.5V to 4.6V Supply Voltage Range

The RT4723P is a highly integrated Boost, LDO and

inverting charge pump to generate positive and

negative output voltage. The negative output voltages

can be adjusted from 0.6V to 2.4V with 100mV steps

by SWIRE interface protocol. The part maintains the

highest efficiency by utilizing a 0.33x/0.5x mode

fractional charge pump with automatic mode transition.

With its input voltage range of 2.5V to 4.6V, the

RT4723P is optimized for products powered by

single-cell battery and the output current up to 30mA.

The RT4723P is available in WL-CSP-15B 1.39x2.07

(BSC) package to achieve optimized solution for PCB

space.

 Single Wire Protocol

 Fixed 4.6V Positive Voltage Output

 Negative Voltage Output from 0.6V to 2.4V per

0.1V by SWIRE Pin

 Auto-Mode Transition of 0.33x/0.5x Charge

Pump

 Built-in Soft-Start

 30mA Maximum Output Current

 Programmable Output Fast Discharge Function

 High Impedance Output when IC Shutdown

 UVLO, OCP, SCP, OTP Protection

 Shutdown Current < 1A

 Available in 15-Ball WL-CSP Package
