The tiny trio includes the LM10504, LM10503 and LM10506, which all boast features like power-saving deep sleep mode, built-in current limit and thermal protection, as well as power-down data protection.
The chips sport three programmable 2.25-MHz DC/DC step-down converters with a purported 95-percent peak efficiency to support core processor function, memory and I/O voltages. The offerings also include a general-purpose, 3-V, 250-mA low-dropout (LDO) regulator for host controller reference.
Each PMIC apparently works with a controller IC to regulate the incoming voltage supply, in order to maximize every watt and make the system more reliable. The small size of the SMD package (2.8-mm2-micro) also helps to save board space, the firm said.
