BL8531C
EXTEND APPLICATIONS
12V STEP-UP APPLICATION
Fig 8
Note: BL8531C’s output voltage is 6V. When the output current is small or no load, the output voltage will be unstable,
use the RZD for flowing the bias current through the zener diode. For step-up application, a diode(for example: 1N4148)
is needed as starter circuit.
STEP-DOWN APPLICATION
Fig 9
Note: In step-down application, use starter circuit as above. 2.5V≤Vzener≤Vout. RST is needed for bias current of
zener diode. This starter circuit also can be used in high voltage step-up application.
