MTC7528S28

DC-DC Converters have a wide range of applications, ranging from the power of small portable electronic devices to the industrial level power of high-power electrical machines. The MTC7528S28 is a DC-DC Converter specifically designed for application in audio electronic equipment. It is a 3-stage, high efficiency, non-isolated DC-DC step-down converter with 25 W of output power.

The MTC7528S28 has built-in low dropout linear regulator and over current protection circuit to ensure extremely low noise levels and a stable output voltage. It can provide up to 25 W of output power in a wide range of input voltages, from 5 V to 36 V. The input and output rectifier diodes rectify and convert AC mains input into DC form.

The basic principle of operation is simple: MTC7528S28 uses the self-oscillating technique and a current-mode control scheme to regulate the power output. It has two stages, an inductor-capacitor (LC) filter and an adjustable output voltage regulator circuit, that work together to ensure precise voltage control and smooth output waveforms. When the voltage of the input AC power source fluctuates, the output voltage of the DC-DC Converter is stabilized and maintained.

The efficiency of the MTC7528S28 is quite impressive. Even when the input voltage is low, the efficiency of the full load is above 90%. The built-in PFC (Power Factor Correction) circuit allows the MTC7528S28 to operate at high efficiency up to 99%. It also has a low standby power consumption, so it is highly energy-efficient and environmental friendly.

The MTC7528S28 is a great choice for converting high voltage AC to low voltage DC for audio electronic equipment. It is designed to be easy to use and has a compact size, making it perfect for a variety of applications in audio equipment. With a wide input voltage range and precise output regulation, the MTC7528S28 is an efficient and reliable DC-DC Converter.
