DC DC Converters:

DC - DC converters are devices that convert a direct current (DC) power source to a different DC power source. DC DC converters are used to provide portable electrical equipment with a consistent and suitable supply of electricity. DC - DC converters are available in a variety of structural forms and may be installed in different enclosures in order to be protected from adverse environmental conditions.

The DVE0125V2PBSC is a DC-DC converter that has a 5:1 input voltage range of 12-60 VDC, an adjustable output voltage of 0.6-1.5 VDC, and a maximum output power of 25W. It uses synchronous rectification technology to reduce power losses and withstand higher ambient temperatures. The built-in control circuit allows a wide range of control modes to be programmed to reach the desired degree of regulation. In addition, it also provides a range of protection features, including current limit, short circuit, under voltage, and over voltage protection.

Application field:

The DVE0125V2PBSC is mainly used in the following application fields: server power supplies, industrial control power supplies, automotive, telecom, and power lighting. The device is suitable for applications where a constant voltage and/or current is required. It is suitable for both continuous and pulsed loads due to the high efficiency of its design.

Working principle:

The DVE0125V2PBSC is a non-isolated DC - DC converter. It takes an input DC voltage and provides an adjustable output voltage. The device works by regulating the input voltage to a suitable output voltage and current. It employs a control circuit, composed of an internal adjustable power switch and control IC, to control the on-off signal to the power switch. The output voltage is regulated by changing the duty cycle of the power switch. This is done by controlling the current in the power switch loop, called the synchronous rectifier current. The frequency of the control switching signal is determined by an internal oscillator, and can be externally set via the external frequency adjustor (FADJ) pin. Additionally, an internal soft-start function can be enabled, which reduces the inrush current that occurs during power up.

The DVE0125V2PBSC can also be configured to provide current limit protection. Using an optional external resistor, the device will limit output current, which is useful for power supply applications that require the limiting of output current. In addition, overtemperature, short circuit protection, under voltage lockout, and overvoltage protection are included in the device.
