產品詳細資訊
The 1CL7662/Si7661 is a monolithic charge pump voltage inverter that will convert a positive voltage in the range of +4.5V to +20V to the corresponding negative voltage of -4.5V to -20V. The ICL7662/Si7661 provides performance far superior to previous implementations of charge pump voltage inverters by combining low quiescent current with high efficiency. The ICL7662/Si7661 has an oscillator, control circuitry, and 4 power MOS switches on-chip, with the only required external components being two low cost Capacitors.
