Frequently Asked Questions
What input voltage range does the TC7662ACPA support for generating a negative rail?
The TC7662ACPA accepts an input voltage from 3 V to 18 V and inverts it to produce a negative output rail of approximately equal magnitude. This wide range makes it compatible with 5 V logic systems, 12 V industrial supplies, and battery-powered designs using 3.3 V or higher rails.
How does the TC7662ACPA compare to inductor-based inverting converters for op-amp bias supplies?
Unlike inductor-based inverting converters, the TC7662ACPA uses a switched-capacitor architecture requiring only 2 external capacitors and no magnetic components. This eliminates EMI concerns from inductor switching and simplifies PCB layout, though the output current is limited compared to inductor-based designs, making it best suited for loads under 40 mA.
Is the TC7662ACPA available in surface-mount alternatives for modern PCB designs?
The TC7662ACPA is offered in an 8-pin PDIP through-hole package. Designers requiring surface-mount footprints should evaluate the TC7662B family in SOIC-8 packaging, which offers equivalent switched-capacitor voltage inversion with a smaller 3.9 mm × 4.9 mm SMT footprint suitable for high-density boards.
What procurement lead time should engineers expect when sourcing TC7662ACPA for production builds?
The TC7662ACPA carries a factory lead time of approximately 8 weeks from Microchip. Production buyers should maintain safety stock buffer or consider authorized distribution channels where stock may be available for immediate shipment to avoid schedule delays.
