Thanks to their low quiescent current of 4 µA, they are suitable for battery-powered applications. The MagI³C-VDMM power supply modules feature a switched-mode DC-DC power supply, including MOSFETs, a driver, compensation circuitry, and a shielded inductor, all within a single package. These modules, which can be used to replace linear regulators, have integrated protection circuitry. They protect against thermal overload and electrical damage caused by overcurrent, short circuits, and undervoltage.
Depending on the load, they automatically switch between PFM and PWM modes. These transitions between operating modes ensure maximum efficiency and minimal output voltage ripple across the entire load current range. To save energy, the power module can be put into standby mode via an additional pin. Together, the POWER GOOD and ENABLE functions also enable power system sequencing.
The new MagI³C-VDMM power supply modules feature a very compact design in a 3.5 x 3.5 x 1.5 mm LGA-9 package. Applications: These Variable Step Down MicroModules are suitable for DC/DC POL applications, industrial and medical applications, test and measurement equipment, powering DSPs, FPGAs, MCUs, and MPUs, as well as I/O interfaces. The MagI³C-VDMM series offers exceptional electromagnetic compatibility. The modules comply with EN55032 (CISPR-32) for Class B radiated interference. Their operating temperature range is -40°C to 105°C.
