DC to DC converters are used for converting one DC voltage to another and are often used in applications where the requirement for output power is greater than the input power. A variety of technique are used to achieve this including voltage turn-on, current control, and pulse width modulation. The REC5-4815SRWZ/H4/A/SMD is a DC to DC converter that belongs to the switch-mode power supply (SMPS) family.

The device consists of two components – a transformer and a controller chip. The transformer is used to transform the input voltage to the required output voltage whereas the controller chip is used to control the duty cycle and to ensure that the output voltage remains stable. The device also includes a number of protection features such as output overload protection, low absorption current with high efficiency, and UVLO (Under Voltage Lock Out) protection.

The REC5-4815SRWZ/H4/A/SMD has a wide input range of 4.5V to 36V DC and an adjustable output voltage from 0.45V to 24V DC. The device is capable of providing output power of up to 20W and is equipped with a built-in over-temperature protection feature that shuts off the device in case of overheating. The device is also equipped with over-current protection that restricts the current from exceeding a preset limit.

In terms of working principle, the REC5-4815SRWZ/H4/A/SMD operates in a principle similar to that of other DC DC converters. An oscillator generates pulses of magnitude proportional to the ratio of the input voltage and output voltage. This ratio is then compared to an internally generated reference voltage and the pulse width is adjusted accordingly.A pulse-width-modulated (PWM) voltage regulator is used to modulate the output voltage; this is done by comparing the output voltage with a reference voltage generated internally. The output of the PWM is then used to drive the switches which control the transformer. The transformer then steps up or steps down the input voltage as required.

Given its wide input range and adjustable output voltage, the REC5-4815SRWZ/H4/A/SMD is ideal for a variety of applications such as power management, voltage regulation, automotive applications,industrial systems, and LED lighting. Its high efficiency and reliable performance make it an attractive choice for design engineers.
