<p>The LM5165YQDRCTQ1 is a wide-input, configurable, synchronous buck switching regulator with integrated MOSFETs. It is engineered to provide high efficiency, superior dynamic response and ease of design-in. It is designed to operate from an input voltage of 4.5V to 60V, making it well suited for high voltage power conversion applications. It offers an adjustable switching frequency of up to 2MHz and integrated over-current protection and load switch-off. It is also capable of providing an output voltage of 0V to 6V. </p><p>The LM5165YQDRCTQ1 is one of the most versatile PMIC (Power Management IC) devices specifically designed for dc-dc switching regulator applications. It is used in a variety of industrial, automotive, and consumer applications ranging from simple DC-DC converters to complex data short-term power supply solutions. It can also be used in powertrain and starter motor applications due to its wide input voltage range and superior efficiency. </p><p>The DC-DC Switching regulator is an electrical circuit used to convert an input voltage to a variable output voltage. The most common version of the DC-DC switching regulator is the buck converter. In a buck converter, the switching regulator will reduce an input voltage to a lower output voltage. The LM5165YQDRCTQ1 is a buck-boost topology which means that it can both step-down and step-up an input voltage, thus providing flexibility in design. </p><p>The LM5165YQDRCTQ1 employs a Pulse Width Modulation (PWM) controller in order to operate. The PWM controller generates a steady stream of pulses that regulate the switching frequency of a power stage consisting of low on-resistance integrated FETs. The PWM controller also senses the output voltage of the power stage and adjusts the switching frequency accordingly in order to maintain the desired voltage. The integrated over-current protection circuit will shut down the LM5165YQDRCTQ1 in the event of an over-current condition.</p><p>Overall, the LM5165YQDRCTQ1 is a highly versatile, cost-effective switcher designed to meet the demands of many high power applications requiring wide input voltage range and a variety of output voltages. Its ability to be configured and its integrated FETs enable the LM5165YQDRCTQ1 to deliver power conversion efficiencies up to 97%.</p>
