Power Supply
for CCD Camera Module
BD6039GU
No.10033EAT02
●Description
BD6039GU is system power supply LSI for CCD camera that supplies all voltage sources for CCD camera.
This IC has Step up DC/DC converter and LDO for CCD sensor, Inverted DC/DC converter for CCD sensor, and LDO (7ch).
REGA, REG1, REG8, REG5 can be connected the power supply independent from VBAT.
Each output voltage has an adjustable by the register, and this IC can correspond to various CCD modules.
A necessary power supply for CCD camera system is integrated into 1chip, and it contributes to space saving.
BD6039GU achieves compact size with the chip size package.
●Features
1) The BD6039GU is equipped with all voltage sources for CCD camera system.
2) Each output has an adjustable voltage; hence this IC can correspond to various CCD modules.
3) The BD6039GU is controlled by I²C BUS format.
4) The BD6039GU employs 4.8mm² chip size package, so this IC achieves compact size.
●Functions
1) Step up DC/DC converter and LDO for CCD sensor (+15V/+14.5V/+13V)
2) Inverted DC/DC converter for CCD sensor (-8V/-7.5V/-7V)
3) 7ch Series Regulator
REG1 : 1.2V, Iomax=210mA
