These primary switched DC/DC converters of MTM Power GmbH, the specialist of individual power supplies, are especially designed for automotive applications and operate according to the push-pull principle, i. e. the input dc-voltage is chopped by two push-pull working transistors with a frequency of approx. 70 - 100 kHz. With the help of a transformer and a secondary linear choke, a galvanically isolated output voltage is produced which is adjusted by pulse-width modulation according to the current mode principle. The converters need no ground load and are short-circuit protected by primary and secondary power limitation. The converters are maintenance free, vacuum potted, prepared for the use in devices with Protection Class II and fulfill the low voltage directive. They show a mechanically and electrically rugged design using SMD-technology and undergo an automatic piece-by-piece test. To ensure a smooth operation, it is necessary to mount the converters on a heat-dissipating surface. The converters are available with 75 W, 120 W, 150 W and 200 W output power and the following connecting types: flying leads or screw connectors.

DCDC converters are the power supply that output a fixed voltage efficiently, converting the input voltage. There are three types of DCDC converters, step-up DC/DC converters, step-down DC/DC converters, and step-up/down DC/DC converters, Multi channel DC/DC converters. They respond to cus to mer needs lining up four types of control. PWM controlled types are highly efficient and excel in the ripple and the noise of Output voltage . PFM controlled types consume only a little power even if operated all the time, especially when lightly loaded. PWM /PFM switchable types work at PFM control when loaded lightly and switch to PWM control when loaded heavily, au to matically.

XP Power announces its JCA series of miniature, board-mounted low power DC/DC converters. Measuring just 1 x 0.8 x 0.4 inches (25.4 x 20.3 x 10.0 mm), the device's shielded metal package is 0.25 inches (6.4 mm) shorter than the 1.25 inch (31.8 mm) industry norm. Using the customary 24-pin DIP layout, the units occupy 20% less printed circuit board area than traditional products. This allows designers to reduce the size of new developments or add in more features, while maintaining the industry standard pin-out makes the converter an ideal drop-in replacement for existing designs.
