TPS65132B5YFFR

The TPS65132B5YFFR from Texas Instruments is a split-rail, single-inductor, dual-output converter IC specifically designed for LCD and OLED display power applications. It supports bipolar LCD bias, enabling it to drive displays requiring both positive and negative voltages.

This device operates with an input voltage range of 2.5 V to 5.5 V. The positive boost converter can output voltages from 4 V to 6 V, while the negative inverting buck-boost converter provides outputs from -6 V to -4 V. It offers a maximum output current of up to 150 mA and boasts high combined efficiency, exceeding 85% at loads above 10 mA and 90% above 40 mA. The output voltage accuracy is maintained at 1% over the full operating temperature range of -40°C to 85°C.

Key features include an I2C interface for flexible control, programmable power-up and power-down sequencing, and programmable active output discharge. The TPS65132B5YFFR is available in a compact 15-DSBGA package, suitable for space-constrained designs. Its split-rail topology and single inductor scheme contribute to a smaller solution size.

Applications for the TPS65132B5YFFR include driving LCD displays for devices with screen sizes ranging from 7 inches to 13 inches. The IC integrates features like adjustable sequencing and output discharge, simplifying the design process for display power management.
