TPS40057-Program verification board

Overview

Chip solution DC-DC chip TPS40057PWPR

The TPS40057 is a high voltage synchronous buck controller with a wide input voltage range (8V to 52V). The TPS40057 offers a high degree of design flexibility and offers user-programmable features including soft-start, undervoltage lockout (UVLO), operating frequency, voltage feedforward, high-side current limit, and loop compensation.

This design is for input 12-24V. Design 3A fuse and 28vTVS circuit.

Output 5.2V8A fixed voltage output. MLCC+ solid capacitor filtering. Guaranteed output ripple

Use 1265 package inductor, 2 TO252 package low ciss Nmos. Guaranteed output current capability.

Input and output are both 5.08 binding posts.

Where can I find software development training for Windows driver development, serial port\USB communication, or industrial control? VC VB DEPHI, etc. are all fine. It takes a long time to learn thoroughly.

Do you have any experts who can achieve a buck-boost IC that can output 30V with an input of 24-36V (preferably 600mA). It would be best if the peripherals are simpler. Please help...
You may not be successful in this life, but you cannot stop growing!
Core Tip: I still remember the first time I interviewed Dr. Kissinger. At that time, I was still studying in the United States and had just started doing talk shows. I had no experience at all. The qu
