Frequently Asked Questions
What input voltage range does the TC7662BEPA support for generating a negative rail?
The TC7662BEPA accepts an input voltage between 1.5 V and 15 V, allowing it to invert supplies from low-voltage coin cells up to standard 12 V or 15 V rails, making it versatile for a wide range of portable and bench-top analog designs.
How does TC7662BEPA compare to TC7660 for high-voltage negative-rail applications?
TC7662BEPA extends the maximum input voltage to 15 V compared to the TC7660's 10 V limit, making it more suitable for designs running from 12 V supplies. Both use the same switched-capacitor topology with 2 external capacitors, so the PCB footprint in the 8-pin DIP package is identical.
Which external components are needed to build a negative supply with the TC7662BEPA?
Only 2 capacitors are required—typically in the range of 10 µF each for the charge-pump reservoir and the output filter—making the TC7662BEPA a very compact solution for dual-supply generation without inductors or transformers.
Is the TC7662BEPA RoHS-compliant and lead-free for use in CE-marked equipment?
Yes, the TC7662BEPA carries a Pb-free (e3 JEDEC moisture sensitivity) designation and is manufactured lead-free, meeting RoHS compliance requirements for equipment sold in the EU and other markets requiring CE or similar environmental certifications.
