TC7662AEPA

TC7662AEPA Description

The TC7662AEPA from Microchip Technology is a charge pump voltage inverter/regulator designed to generate positive or negative fixed outputs from a single input voltage. Housed in an 8-pin DIP package, it operates over a wide input range of 3V to 18V, delivering up to 40mA output current with a switching frequency of 12kHz. This ratiometric, non-synchronous charge pump is ideal for applications requiring compact, efficient voltage inversion or doubling without inductors. Its through-hole mounting ensures robust integration in prototyping or industrial designs, while ROHS3 compliance and REACH unaffected status make it environmentally friendly.
