LMU20P1

Miniaturized Step-Up Power Supply in Package 100 mA Synchronous Boost Converter

Product Details

Description
Features
Parameters
The LMU20P1 is a miniaturized step-up Power Supply in Package (PSiP) offering small size and high efficiency. The PSiP includes an integrated circuit and an inductor in a compact 6-pin LGA package, with dimensions of 2 mm x 2 mm x 0.75 mm (compatible with the DFN package footprints).

The package is optimized for automated assembly by standard surface-mount pick-and-place equipment. The LMU20P1 has a light-load efficiency enhancement function to achieve high efficiency across a wide load range, and features a range of protection circuits that include soft start, over-temperature protection, short-circuit protection and cycle-by-cycle current limit.

The LMU20P1 offers exceptionally low near-field radiation levels and a proprietary start-up circuit to minimize input inrush current.

Applications

Hearing Aids
High-efficiency boost maximizes energy extraction from tiny cells, while ultra-low quiescent current extends overall battery life and maintains clean audio power.
IoT Sensors
Boost enables operation from low/depleting sources, and very low standby power supports long-life or energy-harvested sensing.
Wearables
Boost maintains a stable rail as batteries sag, and high efficiency reduces losses in compact, always-on designs.
Single-/double-cell PV Systems
Boost lifts low, variable PV voltages to a usable level, and low-power operation enables continuous energy-harvested functionality.
Smart Insulin Pens
Boost preserves stable performance as coin cells age, and ultra-low IQ supports multi-year, reliable sensing and dosing.
