DC-DC 48V to 24V 1A Power Supply Buck Chip
DC-DC48V to 24V1A power supply step-down chip is a kind of chip that can step down a DC power supply with an input voltage of 48V to a DC power supply with an output voltage of 24V and an output current of 1A. It is usually used in electronic devices that require 24V power supply, such as industrial automation control systems, communication equipment, etc.
The working principle of DC-DC48V to 24V1A power supply step-down chip is to modulate the input voltage with high-frequency switching through the internal switching tubes and inductors, and to reduce the output voltage through the transformer ratio of AD8061ARTZ-REEL7 transformer. Specifically, it includes the following main parts：
- Input filter circuit: used to filter out the high frequency noise and interference of the input power supply to ensure the stability of the input voltage and small ripple.
- Switching Tube Control Circuit: It realizes high-frequency switching modulation of the input voltage by driving the switching control signal of the switching tube. The switching tube usually adopts MOSFET, characterized by low on-resistance and high switching speed.
- Voltage regulator feedback control circuit: By sampling and comparing the output voltage, the on-time of the switching tube is controlled to stabilize the output voltage at the set value. By adopting the feedback control method, it can realize the precise regulation and stability control of the output voltage.
- Output filter circuit: it is used to filter out the high-frequency noise and ripple of the output voltage to ensure the stability of the output voltage and small ripple.
- Protection circuit: including over-voltage protection, over-current protection, over-temperature protection and other functions, used to protect the chip and the safe operation of the powered equipment.
The features of DC-DC48V to 24V1A power supply buck chip include high efficiency, small size, low power consumption and high stability. It is usually manufactured using surface mount technology (SMT) with high integration and reliability.
In terms of application, the DC-DC48V to 24V1A power step-down chip can be widely used in industrial automation control systems, communication equipment, power electronic equipment and other fields. It can meet the demand for 24V power supply of these equipments and provide stable and reliable power output. Meanwhile, due to its small size and high efficiency, it is also suitable for some application scenarios with strict requirements on size and power consumption.
