In addition, the IRDC3843W can be used as a supply regulator to provide precise output voltage levels with low-ripple noise.

The IRDC3843W has an integrated control circuit and power MOSFET, that helps to eliminate external components. The integrated power MOSFET is designed to operate up to 18A 1Mhz or 1.5MHz. The device is available in a compact SOIC8 or QXFK package that makes designing with it easier and faster.

The IRDC3843W supports a wide input voltage range from 8V to 80V. On-board adjustable voltage sequencers and over temperature protection as well as current limiting are integrated that minimize external components.

This device provides a selectable power-good signal that is compatible with voltage-detecting ICs, which can be used as a system power-on reset. The IRDC3843W has a highly efficient operation, a minimum of external components, and an integrated architecture. It is also has wide environmental operating condition range.

The working principle of IRDC3843W is an advanced synchronous rectified buck power stage which is incorporated into the internal power switch. It utilizes an integrated, low-ripple current source, which sets the current limit during device operation. A current limit firewall built into the power switch is used to monitor the device current.

The voltage across the load is sampled and compared against a reference voltage. The error signal is amplified and used to control the gate drive signal to the power switch. This feedback is used to control the output voltage of the switching regulator. The power switch is shut off if the output current exceeds the programmed current limit or if the device\'s temperature exceeds its maximum rating.

The IRDC3843W has wide usage in regulated DC/DC applications, where its small footprint and low component count make it an ideal fit for end products. Its highly efficient synchronous rectified power stage and low output ripple make it suitable for a wide variety of electronic equipment including instrumentation, LED displays, small portable chargers, and laptop adapters among many other products.
