TPS92641, TPS92640, Synchronous Buck Controllers
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
