9 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

9.1 Application Information

The TPS65632 device is intended to supply the main analog supplies required by AMOLED displays. VPOS is

fixed at 4.6 V, but VNEG can be programmed using the CTRL pin to voltages in the range –1.4 V to –5.4 V. The

SELP2 pin can be used to set AVDD to either 5.8 V or 7.7 V. The device is highly integrated and requires few

external components.

9.2 Typical Application

Figure 8 shows a typical application circuit suitable for supplying AMOLED displays in smartphone applications.

The circuit is designed to operate from a single-cell Li-Ion battery and generates a positive output voltage VPOS of

4.6 V, a negative output voltage VNEG of –4.0 V, and a positive output voltage AVDD of 5.8 V or 7.7 V. The VPOS

and VNEG outputs are each capable of supplying up to 300 mA of current, and the AVDD output of up to 30 mA.
