Working Principle: How Does LTC3614IUDD#TRPBF Operate?

The LTC3614IUDD#TRPBF is a synchronous buck-topology DC/DC switching regulator. The functional blocks of the LTC3614IUDD#TRPBF consist of an internal high-side gate driver, low-side gate driver and DC/DC synchronous buck converter. The high-side gate driver is designed to boost the gate voltage of the internal P-channel MOSFET. The low-side gate driver is designed to boost the gate voltage of the internal N-channel MOSFET.The DC/DC synchronous buck converter block consists of an internal MOSFET pair formed by the internal P-channel and N-channel MOSFETs. The two MOSFETs are connected together in a bridge configuration. When the voltage across the inductor is zero, the P-channel MOSFET is turned on and the N-channel MOSFET is turned off. This allows current to flow from the input to the output. When the voltage across the inductor reaches the threshold voltage set by the internal reference, the P-channel MOSFET is turned off and the N-channel MOSFET is turned on. This allows the current stored in the inductor to flow from the output to the input, thus allowing the output voltage to be regulated at the desired level.

Conclusion: Why Should I Choose LTC3614IUDD#TRPBF?

The LTC3614IUDD#TRPBF is an integrated synchronous buck topology DC/DC switching regulator which is ideal for powering various types of powered electronics and equipment.
