GENERAL PURPOSE DC-DC CONVERTER
3.CONSTANT DEFINITION
V
F
: Forward Voltage of outer Diode.
V
CE(sat)
: Saturation Voltage of M62212 or Saturation Voltage of Current buffer Transistor.
Please setting the Oscillation frequency first and calicurate each constant value.
*1 : Please setting ￠Io about 1/3 to 1/5 of maximum output current.
1
R
2
*3 : Please settng R2 about few Ké
to score of Ké
because output voltage don't
undergo
a influence of input current (Terminla 7).
*4 : Please setting V
DTC(MAX)
to satisfy D
(MAX)
, fixed from caracteristics of D
(MAX)
- V
DTC(MAX)
.
I
CH1
means DTC charge current when start-up(-45μA typ), I
CH2
means DTC charge current
when stable state(-10μA typ), V
OSCL
means lower limit vlage of oscillation waveform
(0.45V typ), and I
DIS1
means DTC discharge current 1(50μA typ).
tstart means time internval when terminal vltage of DTC increase to V
OSCL
from lower voltage
and to start switching at first.
tshort means time interval when output is shut down after output is shorted.
