Power Supply
for CCD Camera Module
BD6029GU
No.10033EAT01
●Description
BD6029GU 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, Series Regulators for DSP 3ch,
CCD I/O 1ch and V-driver 1ch. Each output voltage has an adjustable to the register, and this IC can correspond to various
CCD modules. A necessary power supply for CCD camera is integrated into 1chip, and it contributes to space saving.
BD6029GU achieves compact size with the chip size package.
●Features
1) The BD6029GU is equipped with all voltage sources for CCD camera.
2) Each output has an adjustable voltage, and hence this IC can correspond to various CCD modules.
3) The BD6029GU has 3ch voltage regulators which have adjustable voltage for DSP, and hence
BD6029GU can correspond to various DSP chip sets.
4) The BD6029GU has other 2ch voltage regulators for CCD I/O and V-driver.
5) The BD6029GU is controlled by I²C BUS format.
6) The BD6029GU employs 4.35mm² 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) 5ch Series Regulator
