About the Pcb buck test

Pcb buck test is an open source PCB design by TimGoll, published on GitHub under the MIT license. It is a 4-layer board measuring 124.5 × 61 mm, with 42 components from 24 distinct parts.

Other key parts include the XL1509-ADJE1, TPS62160DSG and MT2492. By type, the board carries 14 capacitors, 10 resistors, 8 connectors, 4 ICs, 4 inductors and 2 diodes.

It belongs with the power & battery designs in this gallery.

From the project

Four different buck circuits on a single PCB benchmarked

To get an understanding of different buck ICs and their drawbacks and benefits I designed this PCB. While all of them worked, some performed better than others. To verify my first impressions while initial testing I benchmarked the ICs over different voltages and currents.

- XL1509-ADJE1 [[datasheet]](https://components.ubitap.com/datasheet/XL1509.pdf) - input voltage range: 4.5..40V - output voltage: 1.23..37V (fixed versions available too) - output current: 2A - switching frequency: 50kHz/150kHz - MT2492…
