RC4190
PRODUCT SPECIFICATION
15
The timing capacitors are set up exactly as in the voltage
dependent oscillator application of Figure 19. The values of
R2, R5, C6, and C4 that are given were chosen to optimize
for the +12V battery conditions, setting the threshold for
oscillator frequency change at V
BAT
= +8.5V.
As given, this power supply is capable of delivering +45 mA
and -15 mA with regulation, until the battery decays below
5.0V.
For information on adjusting the RC4391 to meet a specific
application refer to the Raytheon RC4391 data sheet.
Negative Step-Up Regulator
In the circuit of Figure 22, a bootstrap arrangement of supply
and ground pins helps generate an output voltage more nega-
tive than the input voltage. On power-up, the output filter
capacitor (C
F
) will charge through D2 and L
X
. When the
voltage goes below -2.4V, the RC4190 begins switching and
charging C
F
. The output will regulate at a value equal to the
reference voltage (1.31V) plus the zener voltage of D1. R
Z
sets the value of zener current, stabilized at 1.31V/R2.
