Mingjiada Electronics Supply ADI LTM4630 Dual 18A Or Single Step-Down 36A DC/DC μModule Regulator

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of the [ADI] LTM4630 step-down DC/DC μModule regulator, designed for multi-channel low-voltage, high-current power supplies in applications such as communications, networking, servers, industrial control and FPGA/ASIC systems. Mingjiada provides product selection advice and support for quotations and supply. Specific stock levels, prices, batch sizes and lead times are subject to Mingjiada’s confirmed quotation.

LTM4630 is a dual-channel 18A or single-channel 36A step-down μModule regulator launched by ADI. This module integrates a switch controller, power MOSFETs, inductors and compensation components within a compact package, significantly simplifying peripheral circuitry and PCB layout. It is suitable for board-level power supply designs where space is limited and power integrity requirements are high.

LTM4630 operates over an input voltage range of 4.5V to 15V and supports two output voltage ranges, both from 0.6V to 5.3V (each set by a single external resistor). The device’s high-efficiency design delivers up to 18A of continuous current per output. Only a small number of input and output capacitors are required.

LTM4630 supports frequency synchronisation, multiphase operation, burst-mode operation and output voltage tracking for power rail sequencing, and features an on-board thermistor to monitor device temperature. High switching frequencies and a current-mode architecture enable fast transient response to voltage and load variations without compromising stability.

Mingjiada Electronics specialises in the electronic components supply chain, focusing on ICs, power modules, sensors, storage devices, FPGAs and other components from brands such as ADI, TI, Infineon, ST and Onsemi. With a stable stock supply chain, we can supply all versions of the ADI LTM4630 and support both sample procurement and bulk order fulfilment. In addition to supplying brand-new, genuine products, we also operate an electronic component recycling service and purchase idle chips. We work with factories, solution providers and traders to recycle stock ADI power modules, analogue chips, MCUs and other components, helping to liquidate stagnant inventory through our comprehensive two-way support services.

When selecting power solutions, it is essential to balance current capacity, accuracy, density and reliability. Thanks to its integrated μModule design, flexible dual-channel/single-channel configuration and multi-phase parallel expansion capabilities, the ADI LTM4630 is a mainstream choice for high-current point-of-load buck power supplies.
