From the project
A USB-C PD power-supply design for modular synthesizers, with a separate input board and a synth conversion board for +12 V, −12 V and +5 V.
A USB-C PD power-supply design for modular synthesizers, with a separate input board and a synth conversion board for +12 V, −12 V and +5 V.
This is development hardware. The rail budgets are +12 V / 1.2 A, −12 V / 0.8 A and +5 V / 0.5 A; they are targets, not measured capabilities. The renewed conversion circuit uses AP63201, LT1963A and adjustable LT3015 parts with explicit headroom and thermal qualification conditions.
