LM10503SQ/NOPB Description

Short technical summary and product information.

The LM10503SQ/NOPB from Texas Instruments is an advanced Energy Management Unit (EMU) featuring three configurable, high-efficiency buck converters. This device is designed to supply variable voltages, making it ideal for ASIC and SOC designs that utilize voltage scaling to reduce power consumption.

 

The EMU is digitally controlled via the PWI® 2.0 interface and operates cooperatively with compatible ASICs to adaptively optimize supply voltage. It supports dynamic voltage scaling using frequency/voltage pairs. Key electrical specifications include a wide input voltage range of 3.0V to 5.5V, with Buck 1 offering a programmable output of 0.7V to 1.2V at 2A, and Bucks 2 & 3 providing an adjustable output of 1.0V to 3.5V at 1A each. The regulators achieve up to 96% peak efficiency and operate at a 2MHz switching frequency for smaller inductor sizes.

 

This component is housed in a 36-WQFN (6x6mm) package and is designed for surface mount applications. It operates within a temperature range of -40°C to 70°C. The LM10503SQ/NOPB is suitable for applications requiring multiple supplies in the range of 0.7V to 3.5V and up to 2A, such as Point of Load Regulation for ASICs, NVM Memory drives, servers, networking cards, and video processors.
