MC7660DR2中文资料安森美半导体数据手册PDF规格书

The MC7660 is a pin-compatible replacement for the Industry standard ICL7660 charge pump voltage converter. It converts a +1.5 V to +10 V input to a corresponding -1.5 V to -10 V output using only two low-cost capacitors, eliminating inductors and their associated cost, size and EMI.

The on-board oscillator operates at a nominal frequency of 10 kHz. Operation below 10 kHz (for lower supply current applications) is possible by connecting an external capacitor from OSC to ground (with pin 1 open).

The MC7660 is available in an 8-pin SOIC package in extended temperature range.
