Description :
TP7660 is a DC / DC charge pump voltage inverters ASIC.
Chip can input range is 1.2V ~ 8V voltage conversion into corresponding-1.2V ~-8V output, and only two external capacitors and no inductors, reducing losses, size and electromagnetic interference. The chip's no-load current is small, driving ability (compared with similar foreign products is 50%).
Features
1. Wide input working voltage range: 1.2V～8V
2. High voltage conversion accuracy: 99.9%
3. High power conversion efficiency: 98%
4. Low power consumption: no load current is 20uA (when inputting 5V)
5. Small output resistance: 40Ω (when inputting 5V)
6. Few peripheral components, easy to use: only two external capacitors
7. High electrostatic breakdown voltage: up to 3KV
