Applications
The LM3100MH/NOPB is widely used in industrial automation, telecom equipment, and distributed power architectures where a wide input voltage range (4.5V–36V) must be regulated down to lower rail voltages with high efficiency. It is also well suited for automotive accessory circuits, benchtop instruments, and embedded systems requiring a compact, thermally efficient synchronous buck regulator in a standard SOIC-20 footprint.

Frequently Asked Questions
What is the input and output voltage range of the LM3100MH/NOPB?
The LM3100MH/NOPB accepts an input voltage from 4.5V to 36V (nominal 18V). The output voltage is adjustable via external resistors to supply typical system rails such as 3.3V, 5V, or 12V, with a maximum continuous output current of 1.5A.
What control topology does the LM3100MH/NOPB use?
It uses hysteretic current-mode (CURRENT-MODE HYSTERETIC CURRENT MODE) control operating at a fixed 1MHz switching frequency. This topology provides fast load transient response and inherent cycle-by-cycle over-current protection without external compensation components.
What package does the LM3100MH/NOPB come in and is it RoHS compliant?
The device is supplied in a 20-pin Small Outline Package (SOIC-20, JESD-30 code R-PDSO-G20). It is Pb-free and complies with RoHS/JEDEC e3 moisture sensitivity requirements, making it suitable for lead-free manufacturing processes.
What are typical applications for the LM3100MH/NOPB?
Typical applications include industrial 24V/36V bus step-down regulators, automotive accessory power supplies, telecom and networking equipment point-of-load converters, and embedded computing boards requiring an efficient, integrated synchronous buck solution with minimal external components.
