REC5-053.3SRW/H4/A/SMD-R

REC5-053.3SRW/H4/A/SMD-R is an advanced product in the DC DC Converters category. It is a highly efficient, low-profile, constant current driver IC featuring integrated Buck regulator and switching P-MOSFET. Its simple architecture, low profile, and high efficiency make it an ideal choice for use in a variety of different applications.

The REC5-053.3SRW/H4/A/SMD-R is designed for use as a synchronous step-down regulator. It is capable of converting an input voltage in the range of 2.2 to 28V to an adjustable output voltage from 0.8V to a maximum of 1.3V with an output current capability up to 0.5A. It offers various features such as open and short protection, over temperature protection, and thermal shutdown, making it well-suited for use in automated test systems, set-top boxes, routers, and HDDs.

The working principle of the REC5-053.3SRW/H4/A/SMD-R involves connecting the input and output to the IC. The current is regulated by the external resistor that is connected to the FB (feedback) pin of the IC. When the current begins to flow, it causes the FB pin voltage to drop. This voltage drop is detected by an internal error amplifier, which then adjusts the voltage at the gate of the main power switch. This adjusts the amount of current flowing from the input to the output to ensure that the voltage is maintained at the desired set point.

The main advantages of the REC5-053.3SRW/H4/A/SMD-R include its high efficiency due to low power losses, small size form factor, low profile, and simple design architecture. All of these properties make it suitable for a wide range of applications, such as powering portable electronic devices, LED lighting projects, and automotive designs. The device is also suitable for automotive cold-crank applications, as it uses low power and is rated for higher temperatures.

In conclusion, the REC5-053.3SRW/H4/A/SMD-R is a reliable and highly efficient DC DC converter that is suitable for use in a variety of applications, from automotive designs to powering portable electronic devices. It offers features such as open and short protection, over temperature protection, and thermal shutdown, making it well-suited for a variety of applications.
