DC DC Converters

A DC-DC converter is an interconnected network of components that converts a given direct current input voltage or current into a different direct current output voltage or current. Additionally, some devices do the reverse function, called reverse current converters, which are used in rectifiers. This article will focus on the EXA40-48S1V8-V, a DC-DC converter.

EXA40-48S1V8-V Application Field and Working Principle

The EXA40-48S1V8-V is an adjustable dc-dc converter designed for a wide variety of applications, including DC motor drive systems, servo systems, and similar. It is a compact, small-sized switch-mode power supply. The device is equipped with a maximum input voltage of 38VDC, and its output voltage is adjustable between 1.25 and 48VDC.

The EXA40-48S1V8-V uses a buck-boost switching regulator topology to convert the input DC voltage to the desired output. It contains an inductor, MOSFET power switch, an internal compensation network, and a control circuit. The controller turns the power switch, MOSFET, on and off at a predetermined frequency and duty-cycle, using a pulse-width modulation signal.

When the power switch is on, the input current flows through the inductor and stores energy. When the power switch is off, the inductor energy is released and flows through the internal MOSFET switch to the output. Through the pulse-width modulation process, the output voltage can be regulated to the desired value. This is achieved by controlling the duty cycle or frequency of the PWM signal.

The EXA40-48S1V8-V is built with several features that enable high-efficiency conversions, including programmable and synchronizable switching frequency, soft start, short circuit protection, over-current protection, and thermal shutdown. These features ensure safe, reliable, and efficient operation.
