LV5710V
Bi-CMOS LSI
For camera sensor
Power supply for charge pump
Overview
The LV5710V is power supply for charge pump for camera sensor.
Functions
• Regulating the 5V input by boosting it three-fold with the charge pump to the specified voltage.
• Output voltage variable with external resistor.
• Soft start function incorporated, which reduces the rush current at start of charge pump.
• Timer-latch type short-circuit protective function incorporated.

Output Voltage Setting Method
The output voltage of IC-incorporated LDO can be determined as follows :
VH =
R1+R2
R2
× VREF
For example, to set the output voltage to 12V, set the resistance
Value to R1 = 1070kΩ/R2 = 130kΩ.

Short-circuit Protective Operation
The RO output pin has the short-circuit protective function.
The over-current detector circuit outputs the detection signal when the output current of 50mA (typ) or more flows or
when the output voltage drops below 87.5% (typ). When this detection signal is output continuously for 18ms (typ) or
more, IC determines that there is over-current and stops the output. To reset from the stop state, set the EN pin to “L”,
then set the EN pin to “H” again.

Selecting the Frequency
According to the logic of S0 and S1, the charge pump operation frequency can be changed.
In the case of light load, the reactive power can be reduced by decreasing the operating frequency.
