https://github.com/JRG-Analog/BUFFER2025 A high current open loop buffer Board is designed to use 40x40x100mm aluminum heatsink, with 40mm square fan for cooling.
Description: The circuit is an open loop buffer, that is, no feedback. Phase shift induced by load impedance does not affect stability. This was originally built to test PSRR on devices which require an input capacitor, but it can be used for many other experiments.
Performance: IOUT ±10A; BW 60MHz, rl = 0.5Ω, 1VRMS, +8V/-3V; ZOUT = 250mΩ
