The TC7662AEPA from Microchip Technology is a versatile charge pump voltage converter. It is designed to convert a +3V to +18V input voltage to a corresponding -3V to -18V output, utilizing only two external capacitors and eliminating the need for inductors. This design contributes to reduced cost, size, and EMI.
Key features include a wide operating voltage range of 3V to 18V and an increased output current capability of up to 40mA. The device operates with a nominal oscillator frequency of 12kHz, but can be configured for lower frequencies for reduced supply current applications by adding an external capacitor. Its low output impedance, typically 40 Ohms at 20mA load, makes it suitable for demanding applications.
The TC7662AEPA is pin-compatible with industry-standard devices like the ICL7662 and TC7660, offering a direct upgrade path for designs requiring higher output current or lower voltage drop. It is constructed with CMOS technology and is available in an 8-pin PDIP package, suitable for through-hole mounting.
Applications for the TC7662AEPA include laptop computers, disk drives, process instrumentation, and micro-processor-based controllers. Its ability to generate negative voltages from a positive supply makes it a valuable component in various electronic systems.
