Frequently Asked Questions
What input voltage range does TC7662AEPA support for voltage inversion applications?
The TC7662AEPA accepts input voltages from 3 V to 18 V with a nominal design point of 15 V, allowing it to produce a corresponding negative output rail across a wide supply range suitable for industrial and consumer circuits.
How does TC7662AEPA eliminate the need for an inductor in negative-rail generation?
TC7662AEPA uses a switched-capacitor charge pump topology requiring only 2 external capacitors to invert the supply voltage. This removes the inductor from the BOM, reducing board area and avoiding EMI concerns typical of inductor-based DC-DC converters in sensitive analog circuits.
Is TC7662AEPA available in a through-hole package suited for prototype and low-volume builds?
Yes. The TC7662AEPA is offered in an 8-pin PDIP package with 2.54 mm pin pitch, compatible with standard breadboards and DIP sockets, making it straightforward for prototyping negative-rail circuits before transitioning to SMT alternatives.
What lead time should buyers plan for when sourcing TC7662AEPA in production quantities?
Factory lead time for TC7662AEPA is approximately 8 weeks. Procurement teams sourcing for production volumes should build safety stock or qualify alternative switched-capacitor inverters with a 3 V to 18 V input range to mitigate supply disruptions.
