DC-DC converters allow the transfer of electrical power from one DC voltage level to another and are commonly used for telecommunications, power regulator, battery charging and power conditioning applications. The RI3-0505S/H3 is one such DC-DC converter. This converter is small, efficient and reliable and is suitable for use in many applications.

The RI3-0505S/H3 is a non-isolated buck-boost regulator, designed to provide a constant voltage output with adjustable current limit from an input voltage of 2.5 V DC to 5.4 V DC. The output is adjustable from 1.3 V DC to 4.5 V DC and the maximum current is 5 A (at 0.5 V DC output). It features low quiescent current, hot swap control and adjustable current limit protection.

The RI3-0505S/H3 uses an advanced control scheme to regulate its input and output voltages. It employs an input voltage sensing comparator and an output voltage sensing comparator to adjust the input and output voltages. This provides excellent line and load regulation, even over wide load and input variations. The current limit protection is adjustable to suit different applications.

In addition to the adjustable current limit protection, the RI3-0505S/H3 also features a soft start circuit that limits the inrush current. This helps to protect sensitive loads that may be present. The soft start also helps to protect the converter from thermal and component lifetime damage due to high inrush current.

The RI3-0505S/H3 offers a wide range of protection features including over-voltage, under-voltage, over-temperature and over-current protection. The EMI filter incorporated into the design eliminates common-mode noise and helps to reduce conducted EMI, thus meeting regulatory requirements. The converter is also capable of operating in a wide temperature range (-40°C to +85°C) and provides excellent thermal performance.

The RI3-0505S/H3 can be used in a wide variety of applications such as camera modules, power supplies, LED lighting, portable medical devices, charging systems, and more. The power supply is ideal for use in battery-powered systems as it is highly efficient and can maintain a constant voltage output even in low-battery conditions.

The RI3-0505S/H3 is a highly reliable and efficient DC-DC converter that offers adjustable current limit protection and multiple protection features. It is suitable for a wide range of applications and can operate in a wide temperature range. The built-in EMI filter and current limit protection make it ideal for sensitive applications.
