Renesas (ICL7660SCPAZ) DC/DC Adjustable Charge Pump Voltage Converter

DC/DC Adjustable Charge Pump Voltage Converter, 1.5V to 12V in, -12V to -1.5V/45 mA out, DIP-8 Product Overview The ICL7660SCPAZ is a Super Voltage Converter, monolithic CMOS voltage conversion ICs that guarantee significant performance advantages over other similar devices. They are direct replacements for the industry standard ICL7660 offering an extended operating supply voltage range up to 12V, with lower supply current. A frequency boost pin has been incorporated to enable the user to achieve lower output impedance despite using smaller capacitors. The ICL7660S perform supply voltage conversions from positive to negative for an input range of 1.5 to 12V, resulting in complementary output voltages of -1.5 to -12V. Only two non-critical external capacitors are needed, for the charge pump and charge reservoir functions. The ICL7660S can be connected to function as a voltage doubler and will generate up to 22.8V with a 12V input. They can also be used as a voltage multipliers or voltage dividers. Guaranteed lower maximum supply current for all temperature ranges 100% Tested at 3V Boost pin (pin 1) for higher switching frequency Guaranteed minimum power efficiency of 96% Improved minimum open circuit voltage conversion Efficiency of 99% Improved SCR latch-up protection Simple conversion of +5V logic supply to ±5V supplies Simple voltage multiplication VOUT = (-) nVIN Easy to use, requires only 2 external non-critical Passive components Improved direct replacement for industry standard ICL7660 and other second source devices Applications Power Management Product Information Output Type: Adjustable Input Voltage Min: 1.5V Input Voltage Max: 12V DC / DC Converter IC Case: DIP No. of Pins: 8Pins Output Current: 45mA Adjustable Output Voltage Min: -12V Adjustable Output Voltage Max: -1.5V Topology: Doubler, Inverting Operating Temperature Max: 70°C Product Range: ICL7660S; ICL7660A
