5. Voltage Inverting Type DC/DC Converter
The Start circuit is not needed because the power is supplied from VDD to the IC. Set VIN to 9V-|VCC| or less.
When VCC is -2 V, - 3 V and - 5 V, use the S-8324D20MC, the S-8324D30MC and the S-8324D50MC respectively. Always
connect VOUT to GND without attaching RA, RB.
Set Rb to 60
or more and RE to 6 k or less. The larger RE, the smaller the reactive current through RE and Rb, allowing the
efficiency to be improved. On the other hand, the switching loss of the Tr becomes large and consequently the efficiency will be
worsend. Select RE to ensure high efficiency under operating conditions.
6. Power Supply for GaAs and MR Head
The following are an application negative power supply circuit for GaAs and MR head, and its characteristics when -3V
(-3V
±10%) and -5V (-5V ±10%) are used for the applied power. Set VIN to 9V-|VCC| or less.
