171020601/WPMDH1200601J MagI³C Power Module Product Family VDRM - Variable Step Down Regulator Module DESCRIPTION The VDRM series of the MagI³C Power Modules Family comprise a fully integrated current mode DC/DC power supply with both the switching power stage, control circuitry and passive all in one package These devices also feature built-in compensation circuitry and a soft-start feature for a smooth, safe power up. The 7 PIN PFM is an industrial high power density package with a low profile and a small outline. The VDRM series offers high efficiency and delivers up to 2A of output current with accurate regulated output voltages. It operates from input voltage 6V to 42V. They are available in an innovative package that enhances thermal performance and allows for hand or machine soldering. The VDRM regulators also have on-board protection circuitry to guard against thermal and electrical damage. Thermal shut-down, over-current, overvoltage and under-voltage protections safeguard the regulator and include a short-circuit protection. Peak efficiency up to 90% Current capability up to 2A Wide input voltage range: 6V-42V Wide output voltage range: 0.8V-6V Integrated inductor solution for quick time to market and ease of use Single exposed pad for best-in-class thermal performance Low output voltage ripple Under voltage lockout Protection (UVLO) Programmable soft-start and frequency Thermal shut down, inrush current and output short current protection Temperature range: -40 to 125°C RoHS & REACh compliant Point of Load DC-DC applications Servers, Data and Telecom System power supplies DSPs, FPGAs, MCUs and MPUs I/O interface Data Sheet Würth Elektronik eiSos GmbH & Co.
