    Thank you for contacting TI China E2E forum and choosing our products as part of your solution. Regarding your query, it looks like the output ripple is large from your screenshot. Please review your design and compare with TI EVM schematic. Pay attention to input filter for reducing EMI and output CPOL capacitors in Page 29. www.ti.com.cn/.../snvu646.pdf
