5.6 Power Supply Circuits

The power supply circuits receive the unstabilized DC voltage supplied to CN1 from the
AC adaptor through the Jack PCB via fuse F1 (protective circuit), and the filter circuit.

The 2-channel switching power IC (IC#1) in the circuits converts the unstabilized DC
voltage into a stab5V voltage (logic power supply) and into a stab24V DC
voltage (drive power supply).
