Shenzhen Mingjiada Electronics Co., Ltd. is an authorized supplier of genuine ADI products and a distributor of electronic components in stock. We consistently supply the ADI LTM4675, supporting bulk orders and sample requests. All products are genuine, with a stable supply chain, and are suitable for the development of industrial, communications, and server power supply solutions.
LTM4675 Product Overview
The ADI LTM4675 is a dual-channel 9A buck μModule (micro-module) DC/DC regulator capable of parallel operation with a total current output of 18A. It integrates PMBus digital power management functionality and features a built-in inductor, power MOSFETs, control loop, EEPROM, and a 16-bit ADC. As a highly integrated power module, it requires minimal external components, significantly shortening power supply development cycles. It supports remote configuration, telemetry monitoring, and fault logging, making it the preferred choice for high-density digital power supplies.
