TC7662AEPA

The TC7662AEPA is a charge-pump DC-to-DC Converter converts a 3 to 18V input to a corresponding -3 to -18V output using only two capacitors, eliminating inductors and their associated size and EMI. In addition to a wider power supply input range, the TC7662A can source output currents as high as 40mA. The on-board oscillator operates at a nominal frequency of 12kHz. Operation below 12kHz is also possible by connecting an external capacitor from OSC to ground. It is a pin-compatible upgrade to the industry standard TC7660 charge-pump voltage converter. The TC7662A directly is recommended for designs requiring greater output current and lower input/output voltage drop.
