V24B28E250BS Working Principle

The V24B28E250BS follows the step-down, switch-mode DC/DC conversion principle. In this case, an input voltage is applied to the primary side, and the switch is driven by an integrated on-chip control circuit. The switching pattern enables output voltage to be regulated, and the voltage is also conditioned by a low pass LC filter. This ensures that the output voltage has minimal transients, and has a low ripple factor.

The internal switch is integrated in the topology and is driven by the internal feedback circuit, allowing the converter to operate with a high efficiency. Moreover, the output voltage is adjustable by an external RSET resistor, allowing the user to program the output voltage precisely.

The features of the V24B28E250BS offer a solution with minimal power loss and high reliability for various applications, especially those requiring high voltage step-down conversion. This makes this device ideal for a wide range of markets, such as automotive, telecom, industrial, LED lighting, and solar.
