MagI3C-VDRM 171020601 Power Module
Overview
The 171020601 is a non-isolated variable step-down regulator module from the MagI3C series, designed to deliver up to 2A from a wide input range of 6V to 42V. This PoL converter integrates a controller, power MOSFETs, and a shielded inductor into a single 7-SMD package to simplify PCB layout and minimize radiated EMI. It features a constant-on-time control architecture that provides fast transient response and high efficiency across a wide load range.
Why Choose This Part
This module eliminates the need for external inductor selection and complex compensation design, significantly reducing time-to-market. It offers low output voltage ripple of less than 10mVpp and complies with EN55022 Class B radiated emissions standards due to its integrated shielded inductor. Efficiency remains high at up to 86 percent, supported by an automatic power-saving mode during light-load conditions.
Applications
Key Specifications
Getting Started
To evaluate this part, use the Wurth Elektronik evaluation board or follow the datasheet layout guidelines which emphasize placing the input capacitor as close as possible to the VIN and PGND pins. Output voltage is set via a single external resistor, and the switching frequency is adjustable to optimize for efficiency or footprint size. Ensure the single exposed pad is soldered to a large ground plane for optimal thermal dissipation.
