DC-DC converters are used to efficiently convert direct current (DC) into other forms of direct current, such as different voltages or wattages. These converters are often employed in applications where space is limited, including automobiles, industrial control systems, railway systems, and mobile devices. The PTB48560CAH is a single-conversion DC-DC converter designed to provide up to 60W of output power in a compact, surface mount package.

Features

The PTB48560CAH is a low dropout (LDO) converter that operates from 4.5 to 14V input, with an adjustable output voltage range from 0.7V to 5.1V. It has a wide input range and low power consumption, making it well suited for applications where power efficiency and efficiency are paramount. The integrated power controller ensures maximum efficiency even at light loads. The adjustable output voltage also allows for high flexibility in applications. The device features an under-voltage lockout (UVLO) function, which prevents the converter from being accidentally powered on when the input voltage is too low, as well as a thermal protection system that shuts down the converter when the temperature limit is exceeded. Other features include a low EMI switching frequency, reduced external component count, and a wide temperature range of -40° to +125°C.

Application areas

The PTB48560CAH is designed for use in applications such as smartphones, tablets, and other portable electronic devices, where space and power are limited. In addition, its low EMI switching frequency makes it well suited for use in industrial equipment. Additionally, the wide input voltage range means the device can be used in automotive applications such as battery-powered equipment and automotive bodies.

Working principle

The PTB48560CAH is a DC-DC converter that uses switching technology to transform DC input to a different output voltage. The device consists of an inductor, two switching transistors, two diodes, and four capacitors. The working principle of the converter is simple. When the device is turned on, one of the transistors is switched on and the inductor stores energy in its magnetic field. When the first transistor shuts off, the energy stored in the magnetic field is released and the current flows through the other transistor into the load. The current is then rectified and regulated by the diodes and capacitors. The voltage of the output is regulated by adjusting the duty cycle.

Conclusion

The PTB48560CAH is a highly efficient, single-conversion DC-DC converter that is suitable for use in a variety of applications, ranging from smartphones and tablets to industrial-grade equipment. It has an adjustable output voltage range from 0.7V to 5.1V, a wide input voltage range of 4.5 to 14V, and an integrated power controller to ensure maximum efficiency. The device also has a wide operating temperature and low EMI switching frequency, making it suitable for a broad range of applications.
