Description
The purpose of this design is to demonstrate the key features of STMicroelectronics' L6726A, a new powerful new buck controller. The L6726A allows the simple and cost effective design of complete step-down voltage regulators. Indeed, and provides a full solution by integrating an 0.8 V reference, control logic and protection, and NMOS drivers in an 8-pin package. Moreover, it features a simple control loop with transconductance error amplifier and soft-start programmability. The L6726A evaluation board implements a step-down DC-DC converter, in a four-layer PCB, and demostrates the operation of the device in a general purpose application. The input voltage can range from 5 V to 12 V and the output voltage is fixed at 1.25 V. The application can deliver an output current up to 20 A, with a switching frequency of 270 KHz.
