DC/DC converters are used to convert DC electrical energy from one voltage to another, often with much lower output voltages in the range of 1-10 V. In addition to providing an input-to-output voltage conversion, these converters can also provide a regulated output voltage with very low output ripple. DC/DC converters are widely used in automotive applications, telecom power systems, power supplies, and other applications where a reliable source of power is required.

The NME2415SC is a high-efficiency, ultra-thin DC/DC converter with a wide input voltage range of 7-45 V and a wide output voltage range of 0.8-30 V. It is a tiny part suitable for applications where board real estate is at a premium, and offers long-term reliability and high efficiency. It can handle up to 4 A of current and has an efficiency up to 95%.

Applications

The NME2415SC is designed for applications where tight regulation and high reliability is required, such as telecom power systems, point-of-load (POL) applications, laptop power adapters, and industrial control systems. It is highly suited for situations where power density is important, such as space-constrained and high-temperature environments.

Working principle

The NME2415SC works by converting DC voltage from a rectangular waveform to a trapezoidal waveform using a voltage regulator and a diode bridge rectifier. The input voltage is rectified, and then the Voltage Regulator Mode (VRM) output is used to regulate the output voltage. The output then passes through a Low Dropout (LDO) regulator to prevent over-voltage. Finally, the output is stabilized and the output voltage is lowered using an LC filter. The entire system is then enclosed in a thermal insulation material to protect the device from heat.

The NME2415SC also features various protection features such as: short-circuit protection, over-voltage protection, under-voltage protection, over-current protection, and thermal protection.
