Description

The LM2743MTCX is Texas Instruments’ dual synchronous buck regulator/controller. It targets high-efficiency DC-DC conversion for VRMs and point‑of‑load supplies (CPU/GPU memory, FPGA, telecom, etc.). Key points:
- Two PWM control channels for dual or interleaved buck outputs
- Current‑mode control with feedback to regulate output voltages
- Adjustable switching frequency and synchronization options
- Protection features such as undervoltage, overcurrent/short‑circuit protection, and thermal shutdown
- Typically requires external power MOSFETs, inductor, and capacitor network (buck topology)
- Packaged in TI’s MTCX RoHS-compliant package
Applications include dual-output or interleaved regulators from a common input rail in compute, communications, and industrial equipment. For detailed specs (input range, switching frequency, recommended external components, and exact pinout), refer to the LM2743MTCX datasheet.

Features

LM2743MTCX is a high-efficiency DC-DC buck regulator controller. Key features typically include:
