Working Principles

The MAX660CSA+TGA5 is a voltage converter IC that generates a negative output voltage from a positive input voltage. It operates by using an internal oscillator to drive a charge pump circuit. The charge pump converts the input voltage into a higher voltage, which is then inverted to produce the negative output voltage.
