IK3301

IK3301 Triple DC to DC Converter Control IC for CCD Image sensor DESCRIPTION IK3301 is to be used as power supply control IC for the system that is based on CCD image sensor. IK3301 supplies all the voltages that are needed to operate CCD image sensor, 15V, 5V and –8V, with excellently controlled ripple voltage. The typical power efficiency of this device is 80% at a standard load current. Due to the high power efficiency, the heat dissipation is suppressed, which can be fatal to the image quality of CCD sensor. Excellent voltage ripple and suppressed heat dissipation will be very beneficial for the CCD system that needs high image quality. www.DataSheet4U.com FEATURES Built-in 3-Channel Voltage Output Option : 15V / 5.0V / -8V, 12V / 3.3V / -8V PWM Method High Power Efficiency (80%) Low Heat Dissipation 9~18V Wide Operating Voltage Very Low Ripple Voltage Noise (less than 20mV) High Driving Current (300mA@Vout 3.3V or 5.0V) Small Package Size :16pin MLP (QFN) Simple and Low Cost External Circuit Built-in Protection Circuit for External Damage APPLICATION B/W CCD Camera System Color CCD Camera System Other CCD Image Sensor Power Supply 1 Rev. 01 IK3301 General Description Figure 1 shows the simplified block diagram of IK3301. The device consists of two highly efficient DC-DC converters, a negative charge pump, clock generator to supply clock signals to each circuit and reference voltage generator. The 15V supply voltage is generated by UP voltag...
