FCircuit operation
A zener diode on the feedback pin provides reference
voltage and compensates for temperature changes.
Feedback current is fed from the zener diode to the oscil-
lator.
FApplication example
FOperation notes
(1)
output voltage (33.3V) is required, use a variable resistor
(Murata RVG6P02-104M or equivalent product) with
good temperature characteristics as shown in the ap-
plication circuit. Make sure, however, that the voltage of
the oscillator drive pin does not exceed 42V.
(2)
should have the lowest possible DC resistance (under
10 ) and an inductance of 4.7mH (Sumida Electronics
RC095-472K or equivalent product).
Regulator ICs
When an output voltage greater than the reference
The coil to be connected between pins 2 and 3
Blocking oscillation is provided by connecting the exter-
nal coil L between the oscillator drive pin and the V
The potential at the oscillator drive pin can be raised by
using this oscillation. The output voltage is constant be-
cause the feedback current is always supplied to the os-
cillation circuit.
