What are the key features of TC7660HEPA?

Switched-capacitor charge-pump inverter operating from 1.5 V to 10 V input
Generates negative output voltage equal in magnitude to the positive supply input
Only 2 external capacitors required—no inductors or transformers
8-pin PDIP package enabling fast through-hole prototyping
High-efficiency, low quiescent current suitable for battery-powered portable designs
Pb-free, RoHS-compliant construction meeting e3 JEDEC moisture class

What is TC7660HEPA used for?

The TC7660HEPA is used in analog signal conditioning, op-amp dual-supply circuits, and portable instruments where a negative rail must be generated from a single positive battery or regulated supply of up to 10 V. It is also applied in handheld test equipment, audio preamplifiers, and sensor bias circuits that require a low-noise inverted supply without the complexity of a boost-inverter or transformer topology.

Frequently Asked Questions

How does TC7660HEPA differ from TC7662BEPA for 12 V supply applications?

TC7660HEPA is rated for a maximum input of 10 V, whereas TC7662BEPA extends the limit to 15 V, making TC7662BEPA the correct choice for 12 V supply inversion. For 5 V or lower designs both parts are interchangeable in the same 8-pin PDIP footprint and 2-capacitor circuit configuration.

What output voltage can be expected when TC7660HEPA is powered from a 5 V source?

When supplied with 5 V, the TC7660HEPA ideally produces −5 V on its output through the switched-capacitor charge-pump inversion. In practice, the output is slightly lower due to on-resistance of the internal switches, but for light loads under 20 mA the deviation is typically less than 0.5 V.

Which capacitor values are recommended for stable TC7660HEPA operation?

Microchip recommends 10 µF electrolytic capacitors for both the charge-pump reservoir (C1) and the output filter (C2) for best regulation and low output ripple. Smaller 1 µF to 4.7 µF capacitors may be used for space-constrained designs but will increase output impedance and ripple voltage.

Is TC7660HEPA suitable for equipment that must comply with RoHS Directive 2011/65/EU?

Yes, the TC7660HEPA is Pb-free and carries JEDEC moisture sensitivity code e3, confirming it meets RoHS requirements. The Pb-free flag in Microchip's product database and the e3 JESD-609 code together confirm that no restricted substances are present in concentrations above 1,000 ppm.
