TPS65631DPDR Description

Short technical summary and product information.

The TPS65631DPDR from Texas Instruments is an integrated circuit designed to provide the necessary positive and negative supply rails for AMOLED (Active Matrix Organic Light Emitting Diode) displays. This device is suitable for battery-operated products, featuring a boost converter for the positive voltage (V_POS) and an inverting buck-boost converter for the negative voltage (V_NEG).

Key electrical specifications include an input voltage range of 2.9 V to 4.5 V. The positive output voltage is fixed at 4.6 V with an accuracy of 0.5% from 25°C to 85°C. The negative output voltage is digitally programmable, ranging from -1.4 V to -4.4 V, with a default setting of -4 V. The IC can supply output currents up to 250 mA and offers excellent line transient regulation.

Packaged in a compact 3 mm x 3 mm, 12-pin WSON (DPD) package, the TPS65631DPDR is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C and includes features such as short-circuit protection and thermal shutdown, enhancing its reliability in demanding applications.
