Fig. 5-3 Waveform timing chart (When MiniDisc is operated on rechargeable lithium-ion battery) 4. Generating the REC DRIVE logic voltage 5 V is generated form the CLV circuit voltage 2.8 V by the step-up converter consisting of the REC DRIVE IC506 pin 7 [VG], L514, D502 and C565. The generated 5 V is used for the logic circuit inside IC506.
