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 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 input 5V)
6. Less peripheral components, easy to use: only two external capacitors are required
7. High electrostatic breakdown voltage : up to 3KV
