The NPH15S2405IC is designed to withstand harsh environmental conditions, including extreme temperatures, humidity, and vibration. This makes it well-suited for using in difficult-to-access or harsh environments. In addition, the device is designed to ensure sufficient air flow for cooling purposes.

Working Principle

The NPH15S2405IC is a 6-pin surface-mounted non-isolated switch-mode DC-DC converter. It is designed to convert a wide input voltage range of 6.5-25V to a corresponding output voltage range of 0.6V-19.5V. The typical output current of the device is 2A, with up to 3A peak current output. It has an extremely high efficiency of up to 96%, depending on the load conditions, and a low ripple of less than 100mVpp.

The device combines a synchronous rectifier driver, synchronous rectifier, integrated power MOSFET, PWM comparator, protection circuit, and inductor in an SIP package. The integrated power MOSFET ensures fast switching and low switching losses. The device utilizes current-mode control, which provides fast response, precise output, and minimized EMI. The protection circuit includes over-voltage, reverse-voltage, and short-circuit protections, to ensure reliable and safe operation.

In addition to its exceptional efficiency, the NPH15S2405IC also offers a low-noise operation due to fast switching at high frequency and the use of a proper layout design. The device switches at a frequency of up to 1.5MHz, and thus is not easily influenced by electromagnetic interference. The device operating temperature range is from -40°C to +85°C.
