PH75F280-12

DC DC Converters

DC-DC converters are electronic devices or circuits that are used to convert a source of direct current (DC) from one voltage level to another. The PH75F280-12 is a DC-DC converter that can regulate the current input to a consistent voltage output.

Application Field

The PH75F280-12 is a low-power, low-cost DC-DC converter-based board targeting the consumer, industrial, computer and communication markets. It is ideal for applications like charge pump systems, power switching systems, medical equipment, battery, automotive engine control, computer peripherals, communication systems, and embedded systems. It is also used in controlling the voltage of the 12V supply line and providing the required current.

Working Principle

The PH75F280-12 is a Buck-derived DC/DC converter based on an integrated circuit. It reduces the 18V to 12V electrical energy when the supply voltage is greater than 12V. The main application of the device is for a 12V output voltage system. It is driven by a high efficiency PWM modulated switch with 100 kHz operating frequency. The output voltage is adjustable from 8V to 15V.

The PH75F280-12 regulates the input current to convert it into a consistent output voltage by controlling the pulse width modulation signal with the use of a control circuit. The output voltage is regulated through a set of voltage panels and an error amplifier. The control circuit ensures that the output voltage is held constant even when the input voltage fluctuates. In order to provide over-current protection, the circuit also features protection from short-circuit, over-voltage and other conditions.

The PH75F280-12 is high efficiency, low-cost, and low-power switch-mode DC/DC converter. It provides the desired regulated output voltage, even under changing input voltage and load conditions. It is able to switch between different supply voltages efficiently, which makes it suitable for high-power applications. The PH75F280-12 is also suitable for industrial and automotive applications, as it is able to handle high-current loads and provide protection from electrical surges.
