Overview

The LMZ10500SILR is a high-efficiency 650mA nano-module DC-DC converter from the Power Modules series, designed for space-constrained point-of-load applications. It integrates a synchronous buck controller, power MOSFETs, and the inductor into a single uSiP package, operating from an input range of 2.7V to 5.5V. This module simplifies power design by requiring only a few external capacitors and resistors while providing an adjustable output from 0.6V to 3.6V.

Why Choose This Part

The integrated inductor significantly reduces EMI and simplifies PCB layout by eliminating complex magnetic component placement. Its 2-MHz fixed PWM frequency allows for the use of small ceramic capacitors, while the 3.0mm x 2.6mm footprint saves up to 50% board space compared to discrete buck converters.

Applications

Point-of-Load (PoL) Regulation
Providing localized power for FPGAs, DSPs, and low-voltage microprocessors in high-density PCB layouts.
Optical Modules
SFP/QSFP transceiver modules where high efficiency and extremely small footprints are required.
Handheld Devices
Battery-operated portable electronics that benefit from the 11uA shutdown current and 95% peak efficiency.
Industrial Sensors
Compact sensor nodes requiring a clean power supply with low output voltage ripple and a fixed 2-MHz switching frequency.

Getting Started

For rapid prototyping, use the LMZ10500EVAL evaluation board to test efficiency and ripple across different load conditions. Ensure the feedback resistor network is placed close to the FB pin to maintain regulation accuracy, and follow the datasheet's single-layer power ground guidelines for optimal thermal performance.
