TP7661B
The TP7661BCMOS DC-DC converter is a low-power, easy-to-use power chip. Double voltage usage: When the input negative voltage is -1.0~-8.0V, it can generate -2.0~-16V output; when the input positive voltage is 1.0~8.0V, it can generate -1.0~-8.0V output. Triple voltage usage: When the input negative voltage is -1.0~-6.0V, it can generate -3.0~-18.0V output; when the input positive voltage is 1.0~6.0V, it can generate -2.0~-12.0V output. Three temperature gradient adjustable voltages are optional.
