REC3-1215SRW/H/B/SMD Application Field and Working Principle

The REC3-1215SRW/H/B/SMD series of high efficiency, low output noise DC-DC converters are designed for power output over a wide input voltage range. They can be used in various different applications, such as automotive, industrial, medical, and telecommunications. The devices are available in a variety of package options.

The REC3-1215SRW/H/B/SMD offers high efficiency and excellent output regulation. It features integrated input EMI filter, an internally set converter with a voltage range of 4.5V to 18V and an adjustable output of 1.25V to 10.8V. The device provides output current up to 15A.

In terms of working principle, the REC3-1215SRW/H/B/SMD DC-DC converter uses a buck converter topology, which is an electronic switching power converter. This type of circuit is designed to provide a regulated output voltage despite variations in the input voltage and load. The circuit uses PWM (pulse width modulation) to control the output voltage, by varying the duty cycle applied to the power switch. This is achieved by the use of an oscillator, which rapidly turns the switch on and off.

The REC3-1215SRW/H/B/SMD implements an advanced control algorithm using a fixed switching frequency. This ensures high reliability, with excellent transient response and output voltage accuracy. The converter also features a short-circuit protection system that ensures safe operation and maintains the output voltage at safe levels.
