In an example, a circuit comprising a first inductor coupled between a first node and a second node, a first PMOS having a source terminal coupled to the second node and a drain terminal coupled to a third node, a second PMOS having a source terminal coupled to a ground voltage potential and a drain terminal coupled to the second node, a third PMOS having a source terminal coupled to a fourth node and a drain terminal coupled to the third node, a fourth PMOS having a source terminal coupled to the ground voltage potential and a drain terminal coupled to the fourth node, a NMOS having a source terminal coupled to the third node and a drain terminal coupled to a fifth node, a second inductor coupled between the fourth node and the fifth node, and a controller.

Multi-mode power management circuit

A system that can include a detector that can monitor a voltage at an input of a transistor device over a period of time and provide a signal having a value representative of a capacitance between the input and an output of the transistor device. The system can further include a driver that can have a programmable drive strength and be coupled to input of the transistor device to drive the transistor device at the input thereof. The system can further include a controller that can configure the driver based on the signal to drive the transistor device with a corresponding drive strength.
