13-V to 36-V in, 12-V 125-mA output power module reference design with 0.1% output voltage ripple


Design files


This e-meter applications reference design implements a synchronous buck converter TPS560430 with high efficiency. The efficiency is up to 91.8% at 18-V input and 125-mA output. The output voltage ripple is less than 0.1% of output voltage. The design is available in a compact form factor with 16 mm × 16 mm and one layer placement.
