DC DC Converters

DC–DC converters are electrical circuits that convert a source of direct current (DC) from one voltage level to another. DC–DC converters are found in a variety of applications, including power supplies for personal electronic equipment, telecommunications, automotive requirements and aircraft. One of the commonly used is the RZ-2412S/P DC–DC converter.

Application Field of RZ-2412S/P DC–DC Converter

The RZ-2412S/P DC–DC converter combines the features of low input voltage, low output voltage and low power dissipation to make it suitable for portable equipment. It has wide input voltage range of 4.75-28V and adjustable output voltage of 0.6-22V. The output current of RZ-2412S/P DC–DC converter can be up to 10A. The RZ-2412S/P DC–DC converter is equipped with over-current and short circuit protection, which makes it the perfect choice for applications such as portable battery driven equipment, Wi-Fi transceivers, industrial circuits, and LED lighting.

Working Principle of RZ-2412S/P DC–DC Converter

The RZ-2412S/P DC–DC converter is based on a buck switching regulator. It operates in the way of converting the input dc voltage to higher dc voltage source, and then utilize the pulse width modulation (PWM) to convert it to the higher dc voltage. The operation principle of the RZ-2412S/P DC–DC converter consists of three parts: control, drive, and post regulation. The control part is responsible for providing the reference voltage and clock, and deciding the value of duty cycle. The driving part is responsible to generate the pulse output depending on the duty cycle. The post regulation is responsible for ensuring the output voltage is accurate and stable.

The basic operation of the RZ-2412S/P DC–DC converter is relatively simple. The input voltage is switched through a power switch and the output voltage is regulated through an error amplifier. The power switch provides the pulses of pulse width modulation. In the control loop, the voltage reference and clock are provided. It is responsible for setting the output voltage and the switching frequency. The PWM comparator compares the voltage reference with the error amplifier output to provide the driving signal for the power switch. This signal is then amplified by a power amplifier to provide drive pulses for the power switch.

In the post regulation part, a feedback control is used to ensure the output voltage accuracy. The voltage feedback is connected to the output of the switches to regulate the output voltage by controlling the power switch\'s duty cycle. The output voltage is regulated until the two voltages (reference voltage and feedback voltage) are the same.

The RZ-2412S/P DC–DC converter is a reliable and efficient device for use in a number of applications. Its features make it ideal for use in portable devices, industrial circuits, and LED lighting. With its wide input voltage range, adjustable output voltage, low power consumption, over-current and short-circuit protection, the RZ-2412S/P DC–DC converter is the perfect choice for applications that require efficient and dependable DC voltage conversion.
