Product Overview
Telcom Semiconductor TC7662ACPA high-voltage CMOS charge pump DC-to-DC voltage converter in a standard 8-pin plastic DIP package. Operates from an input voltage range of 3.0V to 18.0V and delivers up to 40 mA of output current. Configurable to invert positive supply voltage to negative (-Vin) or perform voltage doubling (2Vin) using external storage capacitors without requiring inductors.
Key Features
- Input operating voltage: 3.0V to 18.0V
- Output current capability: up to 40 mA
- Typical output resistance: 40 ohms
- Inverts input voltage or doubles input supply
- Pin-compatible upgrade path for standard 7660 and TC7660 series devices
- Commercial operating temperature range: 0°C to +70°C
- Package: 8-pin dual in-line plastic (PDIP-8)
Applications
- Generating negative bias rails on single-supply analog boards and operational amplifier circuits
- Power supply rail generation in breadboard prototypes and modular synth builds
- Direct replacement pull for vintage audio, test equipment, and instrumentation repairs
- Low-current split-rail power systems requiring compact inductorless conversion
Frequently Asked Questions
What is the difference between the TC7662A and the standard 7660?
The TC7662A operates across an extended input voltage range up to 18V, whereas standard 7660 parts are typically limited to 10V.
What operating temperature grade is designated by the ACPA suffix?
The ACPA suffix designates a commercial temperature rating of 0°C to +70°C in an 8-pin plastic DIP package.
Why buy an individual pulled IC instead of a bulk surplus lot?
Buying an individually cataloged and photographed pull gives you the exact component needed for a repair or build without taking on excess inventory. Orders ship for an $8 flat rate, qualify for free shipping at $28, and leave our Idaho warehouse the same or next business day.
Clean negative rails without the noise or footprint of an inductor - an honest workhorse IC ready for the next bench fix.
