This provides low noise operation and low input ripple current. With its ultra-wide range of input voltages, the V375C2H50BN2 is ideal for buck-boost and SEPIC applications.

Working Principle

The V375C2H50BN2 modular DC-DC converter is a step up converter that works on the principle of step up transformation. The input voltage is stepped up by an internal transformer made up of windings and the output voltage is regulated using a control circuit. The converter works by storing the energy from the input voltage in the transformer and then releasing it at a higher voltage. The transformer magnifies the input voltage and the control circuit acts as a governor to maintain the output voltage at a steady level.

The transformer is made up of two windings, an input current winding (primary) and an output voltage winding (secondary). When the primary winding is energized with input voltage, it induces an output voltage in the secondary winding, which is the output voltage of the converter. The input current winding is usually further divided into several smaller windings to reduce losses due to inductance.

The output voltage of the V375C2H50BN2 is regulated by a control circuit. This circuit primarily consists of an error amplifier, a pulse width modulation (PWM) controller and an on-off switch. The error amplifier monitors the output voltage and feeds the information to the PWM controller, which generates a pulse width modulated signal. The signal is used to turn on or off the on-off switch, which regulates the flow of input energy and the output voltage.

In summary, the V375C2H50BN2 is a highly efficient DC-DC converter that can be used in various applications. The input voltage is increased through a step up transformer and the output voltage is regulated by a control circuit. This makes it ideal for buck-boost and SEPIC applications.
