DC DC Converters - REC3-0505DRW/H6/C/SMD-R Application Field and Working Principle

A DC/DC converter is a type of power converter that takes an unregulated direct current (DC) input and produces a regulated DC output. DC/DC converters are found in plenty of everyday applications like car batteries, cellular phone chargers, and solar power converters. There are a wide variety of DC/DC converters available in the market, from simple linear regulators to more complex switched-mode power supplies (SMPSs)

One of the most widely used DC/DC converters is the REC3-0505DRW/H6/C/SMD-R. It is a Dual-output, step down SMPS (Switched Mode Power Supply). It has a wide operating input voltage range of 4.5 VDC to 28 VDC, and is suitable for both unregulated buck or buck-boost applications. The converter is designed to provide regulation of both the voltage and current and delivers an output of 5 VDC at 1A and 3.3 VDC at 0.5A.

The device utilizes a fixed frequency current mode PWM control. The circuit employs ON/OFF control to regulate the current, and the voltage is regulated by varying the ON/OFF duty ratio. This makes the IC inherently insensitive to input and output voltage ripple as well as load transients.

The device operates over a wide temperature range, from -40°C to +85°C and has an output voltage accuracy of ±2.0%. It also features a low standby current consumption and an overtemperature shutdown. The device also has a built in auto-restart feature which allows it to automatically resume normal operation once it has cooled off.

The REC3-0505DRW/H6/C/SMD-R is suitable for a wide range of applications, such as high frequency switched mode power supplies, industrial controls, lighting systems, medical electronics, consumer electronics, computer peripherals, and automotive electronics. Its low cost, small size, and excellent performance make it suitable for many of these applications.
