TP7661A

The TP7661ACMOS DC-DC converter is a low-power, easy-to-use power chip. Doubler mode: 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. Tripler mode: 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. PIN pin is compatible with SCI7661. (TP7661B has the same performance as TP7661A except for no Vreg and RV functions, and the PIN pin is compatible with SCI7661)
