TILMR33630ADDAR
Overview
The LMR33630ADDAR is a synchronous step-down buck regulator capable of delivering up to 3A of output current from an input voltage range of 3.8V to 36V. Operating at a fixed 400kHz switching frequency, it utilizes peak-current-mode control and an integrated compensation network to simplify power supply design. This functional safety-capable IC is housed in an 8-pin HSOIC PowerPAD package with high thermal efficiency.
Why Choose This Part
The regulator features a short minimum on-time of 68 ns, enabling high step-down ratios at higher switching frequencies. It is designed for low EMI and noise, which reduces the need for complex external filtering. Additionally, the HotRod package construction minimizes parasitic inductance and improves thermal performance during high-current operation.

Key Specifications
Getting Started
Start by using the TI WEBENCH Power Designer to generate a schematic and BOM based on your specific Vout and Iout requirements. Ensure the thermal pad is soldered to a large copper ground plane to manage the heat generated at 3A loads. For evaluation, the LMR33630ARNXEVM provides a reference layout that minimizes switching loop area for optimal EMI performance.
