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
