TPS65132 Texas Instruments LCD Bias PMU DSBGA-15

Overview of Single Inductor Dual Output PMU for Displays

The IC Manufacturer proudly presents the Texas Instruments TPS65132, a power management unit (PMU) designed for bipolar LCD and AMOLED displays in portable devices like smartphones and tablets. Operating with a 2.5-V to 5.5-V input, it features a single inductor dual output converter, providing positive (4 V to 6 V) and negative (?C6 V to ?C4 V) outputs with up to 80 mA or 150 mA. Its 15-ball DSBGA package (2.11 mm ?? 1.51 mm) and I2C interface ensure efficient power delivery in compact designs.

Industry experts endorse its performance. ??The TPS65132??s single inductor design and efficiency are critical for our smartphone display solutions,?? says Dr. James Patel, Senior Engineer at DisplayTech Innovations. Its versatility supports a wide range of consumer electronics.

Why Choose This Power Management Unit Over Alternatives?

The TPS65132 excels among LCD bias PMUs due to its single inductor architecture, high efficiency, and compact footprint. Unlike dual-inductor solutions, it uses one inductor for both positive and negative outputs, reducing component count and board space. Its converters achieve over 90% efficiency at 40 mA, surpassing typical PMUs, while a 700-??A quiescent current optimizes energy efficiency in battery-powered devices. The DSBGA-15 package enables ultra-compact PCB layouts, making this Texas Instruments power management IC ideal for small-form-factor displays in smartphones and IoT devices.
