PV75L22-55SX

The PV75L22-55SX is an industrial grade voltage boost module that delivers reliable power output for applications that require it. The device operates with a buck-boost topology and it has two voltage input ports, one power output port, and two secondary output ports. The primary voltage input range for the device is between 9 to 55V, and the secondary output ports have an output range of 8.5 to 84V.

The PV75L22-55SX is designed to deliver up to 225 watts of power with a power efficiency of up to 95%. It utilizes a high frequency synchronous buck-boost converter offering a low system design cost, allowing it to be used in a wide range of applications, including automotive, industrial, and telecom.

The main operating principle of the PV75L22-55SX is a buck-boost topology, which utilizes a series of switches to convert a higher input voltage to a lower output voltage. The power stage includes a series of high frequency switches and a transformer to regulate the conversion ratio. The input voltage is tied to the primary side of the transformer and the output voltage is connected to the secondary side.

The input voltage and output voltage can also be controlled using the control circuit, depending on the application. A feedback loop is used to measure the output voltage and compare it to the required voltage set point. The control circuit then adjusts the switching frequency to ensure the output voltage is within the set point. Depending on the application, the device can also be used in a frequency modulation mode, where the frequency of the switching is adjusted based on the real-time changes in the input voltage.

The PV75L22-55SX can be used for a wide range of applications, such as UPS systems, medical equipment, robotics, consumer electronics, and metering, among others. The device offers a maximum output power of 225 watts, with a power efficiency up to 95 %, adjustable output voltage and adjustable switching frequency.

The PV75L22-55SX can also provide significant cost savings since the power conversion and regulation can be done with a single device, eliminating the need for multiple devices, as well as the high cost of additional components. Additionally, the device has an integrated EMI filter that provides a high level of immunity to electromagnetic interference, allowing it to operate in harsh environments.
