size: 30mm x 13.56mmThe

inductor used here is C3002614 1uH ±20% 9ALiChuang has a 30-15 coupon (

actual test:

output 5V2A

output 5V3A There is a certain temperature rise. Pay attention to heat dissipation

. Under 5V3A, the output voltage can be appropriately increased by 0.1v.

According to the following formula, calculate the R1 R2 value.

When Vout = 5.1V, R1:R2 = 7.5:1. 750k 100k can be selected.
