Würth Elektronik MagI³C-VDRM DC/DC regulator modules

Würth Elektronik has released a series of PCB-mount variable step-down regulator module ICs. The MagI³C-VDRM modules comprise a fully integrated and low-EMI-noise current-mode DC/DC power supply that includes the switching power stage, passive components and control circuitry in a single low-profile and small-outline package.

Providing high efficiencies and accurate regulated output voltage, the series offers a wide input voltage range from 6 to 42 VDC, output voltages from 0.8 to 24 V and maximum output currents from 1 to 5 A, as well as built-in compensation circuitry and soft-start functionality for smooth and safe power up. Delivering stable and low-ripple voltages for components such as microprocessors, DSPs, FPGAs and MCUs and I/O interface applications, typical uses are point-of-load (POL) DC/DC conversion in system power supplies and in server and datacom/telecom applications, as well as in industrial control, measurement equipment and entertainment equipment markets.

In addition to programmable soft start, variable settings include output voltage, switching frequency, stand-by mode and adjustable UVLO (under-voltage lockout) protection. The regulators also have onboard circuitry to guard against thermal and electrical damage, including overtemperature, overcurrent and overvoltage protection, as well as output short-circuit functionality.
