Boardoza TC7660S Symmetrical Breakout Board
Boardoza TC7660S-Symmetrical Breakout Board is a symmetrical voltage regulator that generates both positive and negative voltage outputs from a single input supply. It supports input voltages up to 12 V and can deliver a maximum output current of 15 mA. The VOUT pin provides the same voltage level as the applied input, while the -VOUT pin outputs the negative equivalent of that voltage. Based on the TC7660S charge pump IC, the board combines simplicity with robust performance, making it a preferred choice for engineers and developers who need stable symmetrical outputs with minimal design effort.
This breakout board is well suited for applications that require dual supply voltage without complex power circuitry. It is ideal for operational amplifier circuits in audio and sensor applications, supports portable and battery-powered devices requiring compact and efficient voltage conversion, and ensures reliable operation in industrial equipment used in harsh or variable environments.
