Highly integrated DC-DC modules simplify power design and cut time to market

RS Components is enabling designers to save board space, bill of materials, and development time with the latest Würth Elektronik MagI3C highly-integrated DC-DC converter modules. By integrating the switching regulator, control circuitry and inductor in the same package, the modules require minimal external components. Some models also integrate input and output capacitors and so require no additional components to power the load using factory-default settings. External resistors can be used to customise the switching frequency and start-up timing as required. Evaluation boards are also available for the modules, which help to quickly choose the right model for the desired load. The MagI3C family includes the LDHM high-current LED-driver module. Designed to operate from a 12V, 24V or 48V supply, it can generate an output voltage from 4.5V to 60V and supply 450mA for up to 16 LEDs in series, with PWM dimming. Support for parallel connection allows higher-current applications. The driver is housed in a TO-263 7EP 7-lead surface-mount package, thermally enhanced with a single exposed pad, and is compatible with both ceramic and low-ESR capacitors. MagI3C modules are suitable for a wide variety of applications, including on-board point-of-load converters, powering I/O interfaces, test and measurement instruments, general industrial equipment, medical electronics, and for replacing linear regulators.
