Key Features
- Switched-capacitor charge-pump topology generates negative output from positive 3 V to 18 V input
- No inductor required, reducing PCB area and EMI in voltage-inversion designs
- Wide input voltage range: 3 V to 18 V with nominal 15 V operation
- 8-pin PDIP package for easy prototyping and through-hole assembly
- RoHS-compliant lead-free construction (JESD-609 Code e3)
- Simple design: requires only 2 external capacitors for full operation
Applications
The TC962CPA is used in mixed-signal and analog circuit designs that require a negative supply rail from a single positive power source, such as op-amp circuits, LCD bias generators, and RS-232 interface power supplies. It is also found in portable instrumentation and industrial sensor interfaces where a compact bipolar supply is needed without an inductor. The wide 3 V to 18 V input range makes it adaptable to battery-powered and regulated bench-supply systems alike.

Frequently Asked Questions
What input voltage range does TC962CPA support, and does it need an inductor?
The TC962CPA accepts input voltages from 3 V to 18 V (nominal 15 V) and uses a switched-capacitor charge-pump topology that requires no inductor. Only 2 external capacitors are needed, making it one of the simplest negative-voltage generators available in an 8-pin DIP package.
In what circuit designs is TC962CPA commonly used as a negative-voltage source?
TC962CPA is commonly used to bias dual-supply operational amplifiers, generate the negative rail for RS-232 transceivers, and supply LCD contrast voltage in embedded systems. Its 3 V to 18 V input compatibility covers both 5 V logic and higher-voltage industrial rails, fitting a wide range of analog circuit applications.
How does TC962CPA compare to inductor-based inverting converters for board space and EMI?
Because TC962CPA relies on switched capacitors rather than an inductor, it occupies far less PCB area and generates lower radiated EMI than inductor-based inverting converters. The 8-pin PDIP-8 footprint and 2-capacitor BOM make it suitable for space-constrained designs where a small negative-voltage rail is needed.
What is the lead time and compliance status for procuring TC962CPA in volume?
TC962CPA carries a factory lead time of approximately 8 weeks from Microchip. It is RoHS-compliant and lead-free (JESD-609 Code e3, PDIP-8 package), meeting environmental regulations for industrial and consumer product markets. Procurement teams should account for the 8-week lead time when planning production schedules.
