Vertical Driver LSI for Video Camera CCD Area Image Sensor
Overview
The MN3113F is a vertical driver LSI for a two-dimensional interline CCD image sensor. It features a built-in
power supply circuit that, in conjunction with such
external components as six booster capacitors and two
voltage stabilization capacitors, produces stabilized
+15.0V and –10.0V power supplies from a +5.0V input
and HD pulses.
The MN3113F makes it possible to drive a CCD image
sensor on a single 5 volt power supply.
Features
Single 5 volt power supply
Adjustable output voltage for regulated voltage

Notes
*1: These diodes must have a VF of 0.7V.
*2: These diodes must be Schottky barrier diodes (MA723).
*3: The booster circuit's electrolytic capacitors (C1 to C8) and voltage stabilization capacitors (C9 and C10) must have
little impedance fluctuation at low temperatures.

2. Always use the specified components for peripheral circuits so as to ensure that OVEE and VL do not reverse
potentials when the power is turned off.
As the above sketch illustrates, allowing OV
to exceed VL1 and VL2 by more than 0.7 V produces the risk
EE
of applying a forward bias to the PN junction, turning on the parasitic transistor, and generating an
overcurrent that produces latch-up.
If this phenomenon arises, increase the size of capacitor C8 or decrease the size of capacitor C10 to increase
the OV
time constant.

3. Adjusting boost voltages with SENSE pins
The MN3113F provides the SENSE pins, SENSE1 and SENSE2, for adjusting the boost voltages (V
and V
) with the following procedures.
OUT–
Adjusting the positive boosted voltage
(1) Making V
Insert a resistor, R, between the SENSE1 pin (pin 17) and the V
voltage at the V
OUT+
< 15V
pin is then given by the following formula.
OUT+
V
OUT+'
= VCC x
50kΩ + 100kΩ//R
50kΩ
pin (pin 16). The theoretical output
OUT+
(where 100 kΩ//R is the effective resistance of
the 100 kΩ resistor and R connected in parallel.)
For example, if R is 50 kΩ,
50kΩ + 33.3kΩ
= 5 x
50kΩ
= 8.3V
(2) Making V
OUT+
> 15V
V
OUT+'
Insert a resistor, R, between the SENSE1 pin (pin 17) and the GND pin (pin 42).
V
OUT+'
= VCC x
50kΩ//R + 100kΩ
50kΩ//R
OUT+
Adjusting the negative boosted voltage
(1) Making V
OUT–
< –10V
Insert a resistor, R, between the SENSE2 pin (pin 39) and the GND pin (pin 42).
V
= VCC x
OUT–'
(2) Making V
OUT–
> –10V
Insert a resistor, R, between the SENSE2 pin (pin 39) and the V
V
= –VCC x
OUT–'
50kΩ//R + 50kΩ
50kΩ//R
50kΩ + 50kΩ//R
50kΩ
pin (pin 40).
OUT–
For example, if R is 50 kΩ,
V
OUT–'
50kΩ + 25kΩ
= –5 x
50kΩ
= –7.5V
Note, however, that the above formulas are mere guidelines, that the internal resistances vary between
samples, and that therefore each sample will have to be adjusted.
Note also that booster circuit capacity and output load current impose limits on adjustments for boosting
V
above 15V and V
OUT+
(The maximum possible adjustments are 20V for V
below –10V.

and –15V for V
