TC7660SEOA713

Microchip Tech · Charge Pumps · SOIC-8

TC7660SEOA713 from Microchip Tech, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 BOOST input Frequency boost control pin; connect to V+ to increase switching frequency from 10 kHz to 45 kHz, otherwise leave open or connect to ground.
2 CAP+ passive Positive terminal for external charge pump flying capacitor; recommended to use low ESR capacitor for efficient charge transfer.
3 GND power_in Ground terminal serving as input and output zero volt reference.
4 CAP- passive Negative terminal for external charge pump flying capacitor; proper polarity is imperative when using polarized capacitors.
5 VOUT output Output voltage terminal supplying negative DC voltage; charge pump output capacitor positive terminal connects here for output filtering.
6 LV input Low voltage control pin ensuring oscillator operation below 3.5V input; connect to GND for V+ < 3.5V, otherwise leave open to prevent damage.
7 OSC input Oscillator control input for frequency modification; bypass with external capacitor to slow oscillator or apply external clock with 1 kΩ series resistor.
8 V+ power_in Positive power supply input accepting 1.5V to 12V for inverting voltage conversion; bypass to ground with low ESR capacitor.
