The RP90Q-2424SRW/P is a DC-DC converter, or a DC to DC power regulator designed to provide a regulated power output from an unregulated input source. This type of converter is often used in applications where regulated power is needed, but where an unregulated power source is available. The RP90Q-2424SRW/P is a mini-sized step-down, buck converter, which means it takes an input voltage from a higher power level, and steps it down to a lower, regulated output. The two key components of its design are:

High Switching Frequency

The RP90Q-2424SRW/P has a high switching frequency, up to 1.2MHz, with a wide input range from 4.5V to 24V, and an output voltage of 0.6V to 21V. This allows the converter to efficiently regulate power from any input source, while ensuring a constant, regulated, output voltage. This is achieved by switching the input voltage on and off at a very high frequency, and then controlling the peak voltage via pulse width modulation (PWM).

Internal Protection Circuit

The RP90Q-2424SRW/P also features an internal protection circuit. This circuit monitors the output voltage, and if it exceeds the specified level, the circuit will shut down the converter to prevent any potential damage or power loss. This allows the converter to work consistently and safely, even under extreme operating conditions.

Application Fields

The RP90Q-2424SRW/P is commonly used in a variety of applications, such as mobile phones, automotive electronics, industrial controls, power supplies, medical applications, and LED lighting. It offers high efficiency, small size, excellent protection and low ripple. Additionally, its high switching frequency and wide input range make it a good choice for applications that require a high level of performance.

Working Principle

The main component of the RP90Q-2424SRW/P is a buck converter. This is a type of DC to DC converter that receives an input voltage, typically from a higher DC power source, and converts it to a lower voltage at a constant current. The input voltage is switched on and off at a very high frequency, and then the peak voltage is modulated using pulse width modulation (PWM). The output voltage is then regulated by controlling the pulse width, and the efficiency of the conversion depends on the frequency of the switching. The RP90Q-2424SRW/P offers high efficiency conversion and excellent protection under load, making it an ideal choice for a variety of applications.
