LP87561IRNFTQ1 General Description

One of the standout features of the LP8756x-Q1 is its automatic PWM to PFM operation, known as AUTO mode, which ensures efficiency across a wide range of output currents. Additionally, the device supports remote differential-voltage sensing for multiphase outputs, enabling precise voltage regulation by compensating for IR drop. The LP8756x-Q1 also allows for synchronization with an external clock to minimize disturbances
