LSC0580

Power Converter for Vertical Point-of-Load Power Delivery

Product Details

Description
Features
Parameters

The LSC0580 is a fully integrated Power-System-in-Package designed for high-current power applications. It features Lotus Microsystems’ proprietary architecture. The device comes in a thin package integrating all passive components needed for operation.

With its high current capability and targeted output voltage range of 0.4 V to 1.2 V, the LSC0580 is ideally suited for vertical power delivery applications, including AI and ML accelerators. The package height also makes the device well suited for a new generation of compact, high power density power supplies designed for vertical power delivery networks (PDNs).

The LSC0580 integrates several protection features, including under-voltage lockout for auxiliary power supplies, over-temperature protection, and short-circuit protection.

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.

Applications

Optical Transceivers & Modules
Ultra-low-noise power delivery maximizes optical signal integrity, enabling cleaner modulation, tighter eye diagrams, and higher data rates.
Computing Point-of-Load Power
Exceptionally low output ripple ensures stable, quiet rails for sensitive CPUs, ASICs, and FPGAs –⁠⁠⁠⁠⁠⁠ ideal for high-precision digital systems.
