VE-B5L-CW-F2

DC to DC converters are commonly used to transfer electrical energy from a higher DC voltage to a lower DC voltage with high efficiency. This type of power conversion is particularly useful in applications such as electronic equipment or battery-powered systems. The VE-B5L-CW-F2 series DC to DC converters are a range of wide input voltage, high regulation and high efficiency converters. They have been designed to meet the power system requirements of demanding applications such as instrumentation, telecommunications, and commercial electronics.

The VE-B5L-CW-F2 series DC to DC converters offer high reliability and long life due to their wide operating temperature range of -40°C to +85°C. These units are designed to provide up to 0.5W of output power, with an 18V to 36V input voltage range and 24V to 28V output voltage range. The power density ranges from 0.2W/cm3 to 60W/cm3, with ultra-low quiescent current consumption and high efficiency of up to 88%. The converters also feature wide regulation and protection against short circuit, over current and over temperature conditions.

The principal of operation of the VE-B5L-CW-F2 series DC to DC converters is based on the control of an inductive switch, typically a power MOSFET, to convert the input signal. The device is connected in series with an inductor and a capacitor, and is used to regulate the output voltage. The inductor acts as a storage element, storing energy when the switch is enabled and releasing it to the output when the switch is off. The size of the inductor is chosen according to the desired output power, input voltage, output voltage and operating frequency. The capacitor is selected in order to filter the output voltage and also to limit inrush current when the converter is turned on.

The output voltage of the converter is regulated by a control loop which monitors the output voltage and adjusts the duty cycle of the switching device in order to maintain a constant output. The control loop works in two phases; at start-up the loop sets the initial output voltage, and after this the output voltage is kept constant by monitoring the output voltage and adjusting the duty cycle of the switch accordingly.

The VE-B5L-CW-F2 series DC to DC converters are suitable for various applications such as mobile phones, notebook computers, cameras and other consumer electronic products. They are designed with high efficiency, wide input voltage range, high regulation and long life in mind. These converters are an ideal choice for power efficient applications where reliability and long life are of paramount importance.
