Micfrochip (TC7662BCOA) DC/DC Adjustable Charge Pump Voltage Converter

DC/DC Adjustable Charge Pump Voltage Converter, 1.5V to 15V in, -15V to -1.5V/20 mA out, SOIC-8 Product Overview The TC7662BCOA is a charge pump DC-to-DC Voltage Converter for data acquisition systems. It converts a +1.5 to +15V input to a corresponding -1.5 to -15V output using only two low-cost capacitors, eliminating inductors and their associated cost, size and EMI. The on-board oscillator operates at a nominal frequency of 10kHz. Frequency is increased to 35kHz when pin 1 is connected to V+, allowing the use of smaller external capacitors. Operation below 10kHz (for lower supply current applications) is also possible by connecting an external capacitor from OSC to ground (with pin 1 open). The TC7662B contains all the necessary circuitry to complete a negative voltage converter, with the exception of two external capacitors which may be inexpensive 1µF polarized electrolytic types. 96% High power efficiency Easy to use - Requires only 2 external non-critical passive components Improved direct replacement for industry standard ICL7660 and other second source devices Applications Commercial, Test & Measurement, Power Management Product Information Output Type: Adjustable Input Voltage Min: 1.5V DC / DC Converter IC Case: SOIC No. of Pins: 8Pins Output Current: 20mA Adjustable Output Voltage Min: -15V Adjustable Output Voltage Max: -1.5V Topology: Doubler, Inverting Operating Temperature Max: 70°C
