HV830DB1 Schematic
Typical Performance
The circuit in Figure1 is optimized to drive a 8.0in
from a 3.0V to 3.3V power supply. The specifi c components
used in Figure 1 are: Lx = 220µH Murata (LQH43CN221K01),
and C
Notes:
1. Lamp brightness can vary by type and manufacturer.
2. The recommended inductor is a Murata LQH4N series. Other inductors may be used, however, different inductor characteristics (especially series
