DC-DC converters are utilized to supply a fixed DC voltage from an AC or a DC source. They can be used in a variety of applications, such as providing an isolated power source to components in an electronic circuit, maintaining a constant voltage level for powering sensitive electronic equipment, increasing the voltage level of a signal or voltage supplied by a battery to match that of a motor, and providing a regulated output from a low voltage to a higher voltage circuit, such as when utilizing an integrated circuit (IC) in a computer. TEN 40-4811N is a series of DC-DC converters.

TEN 40-4811N offers high-efficiency, high-power density, and wide-input voltage range. For its input range, it operates from 10 VDC up to 48 VDC, and its output voltage is regulated between 10 VDC and 32 VDC. It also features an adjustable output voltage across its range. This device is also RoHS compliant and accepts up to 7.5 A of output current with a full-load test condition of 40 VDC. It has a power density of 4.2 W/in.3 and thermal protection, making it suitable for a variety of applications such as industrial, automotive, medical, telecommunications, and defense.

The working principle of the TEN 40-4811N is based on a switched-mode power supply (SMPS) topology. A basic SMPS is a fast rectifier followed by a power switching regulator and an output filter. The fast rectifier provides low ripple and distortion and the power switching regulator provides high efficiency and small form factor. The output filter is used to create a steady DC voltage by removing the fast switching frequency generated by the power switching regulator. The TEN 40-4811N is designed with a synchronous rectifier and PWM controller for its power topology.

The TEN 40-4811N is controlled by the power PWM controller which is designed to regulate the output voltage by switching a MOSFET at a frequency of 375 kHz. The PWM controller includes a voltage error amplifier and a MOSFET driver circuit. The MOSFET driver circuit is used to turn ON/OFF the MOSFET switch in response to the error amplifier output. The error amplifier output is determined by a voltage sense resistor which sets the output voltage. The output voltage is then compared to an internal reference voltage and the error amplifier adjusts the duty cycle of the MOSFET switch accordingly. This allows the output voltage to remain constant despite variations in the input voltage.

The TEN 40-4811N can be used in a variety of applications where a constant DC voltage is required. It is especially suitable for industrial applications due to its wide input voltage range and high power density. It can also be used in automotive, medical, telecommunications, and defense applications due to its low noise, high efficiency, and small form factor. The TEN 40-4811N is also RoHS compliant, which makes it suitable for environmentally friendly applications.
