General Description

The TPS92640 and TPS92641 devices are highvoltage, synchronous NFET controllers for buckcurrent regulators.

Output current regulation is based on valley current-mode operation using a controlled on-time architecture.

This control method eases the design of loop compensation while maintaining nearly constant switching frequency.
