Ripple current regulationTPS60151DRVR has the ability to automatically adjust the switching frequency in order to ensure ripple current regulation in the output capacitor. This ensures efficient operation even under varying load and input voltage conditions.2. Low component countThe device comes with minimal required external components, reducing the system component costs by up to 50%.3. Fast response timeTS60151DRVR features a fast response time, allowing it to quickly and accurately adjust the output voltage to the desired value.4. High efficiencyThe device features a high efficiency of up to 96%.5. Low output voltageTPS60151DRVR is capable of delivering an output voltage as low as 0.8V. This makes it ideal for applications that require low output voltage.Working PrincipleTPS60151DRVR works by converting the incoming DC input supply into a regulated DC output result. The process is achieved by switching the MOSFETS between the two states. During a cycle, the integrated MOSFET driver signals the MOSFET to switch on and current flows through the inductor, creating a magnetic field. The MOSFET then switches off and the field collapses, causing a spike in the current and creating an output voltage. The output voltage is then controlled by the controller by varying the duty cycle of the MOSFET switch.ConclusionThe TPS60151DRVR is a DC-DC synchronous buck controller designed for minimal component count and maximum space-saving. It is well suited for a wide range of applications due to its low component count, fast response time, high efficiency and low output voltage capabilities. The device operates by converting the incoming DC supply into a regulated output voltage through MOSFET switching.
