DC-DC converters are widely used in various electronic systems, from automotive applications to consumer electronics. The REC5-1205SRW/H2/A/CTRL is a switched-mode DC-DC converter designed for low input voltage and high output current applications. It provides a regulated output voltage of 12V with up to 5A of current. The device operates between 4.5V and 15V input voltages, enabling applications that require high efficiency with wide input voltage range.

The REC5-1205SRW/H2/A/CTRL is a non-isolated, buck-type DC-DC regulator which works in two phases. In the first phase, the reason starts at a frequency of 300 kHz and the internal MOSFETs form a power switch. During this phase, a current-sense amplifier senses the current through the switching transistor and feeds it back to the integrated PWM controller. The PWM controller then adjusts the duty cycle of the power switch until the output voltage is regulated to the desired value.

The second phase is the recovery phase, in which the MOSFETs are turned off but the current still flows through the inductor. During the recovery phase, the current is gradually reduced and the output voltage is maintained. The switching frequency is adjustable from 200kHz to 350kHz by an external resistor to optimize efficiency and transient response.

The REC5-1205SRW/H2/A/CTRL is ideal for applications requiring very fast load transient response, such as voltage regulator modules and point-of-load converters. It provides high efficiency, high output current, wide input voltage range, and fast load transient response. The device is also protected from short-circuit, over-voltage, and over-temperature conditions.

In summary, the REC5-1205SRW/H2/A/CTRL is a non-isolated, high efficiency, buck-type DC-DC converter designed for wide input voltage range and high output current applications. It has adjustable switching frequency and fast transient response, and is protected from short-circuit, over-voltage, and over-temperature conditions. It is ideal for voltage regulator modules and point-of-load converters.
