Waldenburg (Germany) – The MagI³C-VDMM power module product family from Würth Elektronik continues to grow: The three variable step-down MicroModules for input voltages from 2.5 V to 5.5 V and adjustable output voltages from 0.6 V to 4 V are available in pin-compatible 1 A, 2 A, and 3 A versions. The modules achieve a peak efficiency of up to 96 percent. With their low quiescent current of 4 µA, they are also suitable for battery-powered applications.
MagI³C-VDMM power modules represent a fully integrated DC-DC power supply that includes a switching regulator with integrated MOSFETs, as well as a controller, compensation, and a shielded inductor – all in a single package. The modules, which can replace linear regulators, are equipped with integrated protection circuits. They protect against thermal overload and electrical damage caused by overcurrent, short circuit and undervoltage. Depending on the load, they automatically switch between pulse frequency modulation (PFM) and pulse width modulation (PWM) modes. These mode transitions ensure optimal efficiency and output voltage ripple at all load currents. To save energy, the power module can be set to resting mode using an additional pin. Together, the Power-GOOD and EN functions also enable power sequencing. The new MagI³C-VDMM power modules are highly compact with their 3.5 x 3.5 x 1.5 mm LGA-9 package.
Applications
Variable step-down MicroModules are suitable for point-of-load DC-DC applications, industrial and medical equipment, test and measurement devices, for powering digital signal processors (DSPs), field-programmable gate arrays (FPGAs), microcontroller units (MCUs) and microprocessor units (MPUs), as well as I/O interfaces. The MagI³C-VDMM series features excellent electromagnetic compatibility. The modules comply with EN55032 (CISPR-32) Class B for radiated emissions. Their operating temperature range extends from -40°C to 105°C.
The new members of the MagI³C-VDMM family are available from stock, even in larger quantities. Free samples can be requested at any time.
