The TPS56637RPAR with Switching Voltage Regulators, manufactured by Texas Instruments, is a 4.5-V to 28-V input 6-A synchronous buck converter with ULQ-mode, packaged in a 10-VQFN-HR -40 to 125 temperature range. It features an integrated high-side driver, soft-start, and power-good indicator. It can provide up to 6A of output current with excellent line and load regulation and low output ripple voltage. It is suitable for applications such as LED lighting, computing and server systems, and enterprise networking. It is designed to reduce component count and improve power capability and reliability compared to discrete solutions.
