This article will provide information on the application field and working principle of NPH25S2405IC.

Application Field

NPH25S2405IC is a DC-DC switching converter manufactured by Nicoya Technology. It is a boost converter integrated with an MOSFET, an inductor, and a voltage regulator. The rated working voltage of NPH25S2405IC is between 2.4V and 24V. It has a wide input voltage range from 3V to 28V, with an output voltage adjustable between 2.5V to 16V. In addition, it has a power output range between a maximum of 25W and a minimum of 6W due to its high-efficiency power transistor. This makes it suitable for power supplies with high current and low output ripple, such as in automotive electronics.

NPH25S2405IC is also suitable for medical devices that require a reliable power supply due to its high efficiency and wide temperature range that allows the device to operate in extreme conditions. In addition, it provides a precise output voltage control with its low-grade ripple voltage and low-power standby mode.

Working Principle

The working principle of NPH25S2405IC is based on the boost switching regulator. In this circuit, an inductor and a voltage regulator are connected to a MOSFET in series. An input voltage is applied to the circuit, and the inductor stores energy to boost the input voltage to the desired output. The voltage regulator then maintains a stable output voltage. When a current reaches the maximum output limit, the MOSFET will automatically shut off the circuit.

To achieve an output voltage higher than the input voltage, the switching MOSFET is repeatedly switched at a very high frequency, allowing the input voltage to be multiplied. This process is known as Pulse Width Modulation (PWM) switching. PWM also helps in reducing power consumption, increasing system efficiency, and minimizing electromagnetic interference.

The NPH25S2405IC is a switching regulator circuit, which works by controlling the duty cycle of the inductor. The duty cycle of the inductor is determined by the output voltage, and is determined by the control signals sent to the voltage regulator. The voltage regulator receives feedback signals and corrects the output voltage as needed.

NPH25S2405IC is a reliable and cost-effective DC-to-DC converter and its flexible design allows it to be used in a variety of applications ranging from automotive electronics to medical electronics. Its wide input voltage range, low ripple voltage, high efficiency, and wide temperature range make it suitable for use in power supplies that require high current and low output ripple, such as in medical devices.
