DC–DC converters are electrical circuits that convert a source of direct current (DC) from one voltage level to another, usually with higher efficiency than a transformer. The JTF0848S05 is a DC–DC converter that is part of a series of high efficiency, high power density converters, with both step down and step up features. Its output voltage is adjustable and it can provide high speed turn-on control.

Application Field

The JTF0848S05 is a perfect fit for applications such as automotive, communication systems, high-power industrial machinery, medical equipment, and various power supply systems. Due to the high power density of the JTF0848S05, it is capable of delivering a high output power with a fairly small size, making it an ideal solution for lightweight and small form factor devices. It is also quite efficient, able to quickly and reliably provide the required output power using a minimum of energy.

Working Principle

The JTF0848S05 is a pulse-width-modulated (PWM) type DC-DC converter. It works by alternately switching ON and OFF an internal switch, which in turn converts the input DC voltage into a pulsed waveform. This waveform is then filtered, rectified, and regulated to generate the output voltage. The frequency of the ON/OFF switching can be adjusted to optimize the efficiency as well as the level of noise generated by the converter.

The JTF0848S05 can accurately set and control the output voltage, eliminating the need for bulky voltage regulators. Furthermore, it features overvoltage and overload protection to safeguard connected equipment from damage. Not only that, but it has an internal soft-start feature that allows for a gradual rise in the output voltage, preventing excessive inrush current. This makes it a highly reliable solution for any application.
