DC-DC converters are electronic circuits that are designed to transfer energy between two electric circuits via an intermediate power link. They offer a variety of benefits, such as improved efficiency, flexibility, conversion of output voltage, and small size. The V28C28H100BS2 is one of the most popular DC-DC converters on the market, with a wide range of applications and a simple working principle.

The V28C28H100BS2 is a patented, ultra-high-efficiency buck-converter solution sourced from Volterra Semiconductor. The design offers significant gains in power efficiency and flexibility compared to conventional linear regulators. This is thanks to its innovative circuit architecture, which pairs its high-configurability with low power losses and low-noise operation.

The V28C28H100BS2 is a monolithic buck converter with an adjustable output voltage and wide range of input voltages. The device integrates a pre-driver, high current stepping motor driver, a wide input voltage range (12V to 28V), an adjustable output voltage (1V to 6V), and very low quiescent current. This makes the device ideal for applications in the telecommunication, industrial control, healthcare, home appliance, transportation, and automotive industries.

The V28C28H100BS2 converter operates with a single switching buck architecture, with integrated features such as pre-boost and diode emulation allowing for higher efficiency over traditional solutions. It includes a high-speed internal clock which is optimized for transient response and low-dropout operation. In addition, the device features a low input current which helps increase power savings. The built-in EMI filter also helps to reduce potentially disruptive noise, making this converter suitable for applications requiring stringent electromagnetic interference (EMI) specifications.

The device offers significant power savings (over 80%) and low power losses due to its high-performance integrated FETs. It comes with an adjustable switching frequency (up to 1MHz) and thermal shutdown protection. The V28C28H100BS2 also offers adjustable dead time of 10ns to enable smooth current overshoot when the device is first switched on.

In order to operate, the V28C28H100BS2 converter requires two DC power supplies – a primary (input) voltage source and a secondary (output) voltage source. The input voltage source is connected between the converter’s “BOOST” and “GND” pins, while the output voltage source is connected between the converter’s “EN” and “OUT” pins. Once the input and output supplies are connected, the converter will begin to regulate the output voltage based on the input voltage, allowing for flexible and efficient power conversion.

The V28C28H100BS2 is a highly versatile, flexible, and efficient DC-DC converter solution. Its wide range of input voltage, adjustable output voltage, and low power losses make it an ideal choice for applications ranging from automotive to medical and industrial use. The device also provides superior EMI performance, enabling it to be used in applications requiring low-noise operation.
