TC7660EOA713

Microchip Tech · DC-DC Converters · SOIC-8

TC7660EOA713 from Microchip Tech, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No connection; the pin has no electrical function and is left unconnected.
2 CAP+ passive Positive terminal of the charge pump (flying) capacitor; a low ESR capacitor is recommended, and larger values lower the output resistance.
3 GND power_in Input and output zero-volt reference; it must be connected to the LV pin for supply voltages below 3.5V.
4 CAP- passive Negative terminal of the charge pump (flying) capacitor; proper orientation is imperative when using a polarized capacitor.
5 VOUT power_out Negative output voltage connection for the charge pump output capacitor; a low ESR capacitor is recommended, and larger values lower the output ripple.
6 LV input Low voltage pin that ensures proper oscillator operation for input voltages below 3.5V; it must be connected to GND for V+ below 3.5V and otherwise left floating.
7 OSC input Oscillator control input used to slow down or speed up the oscillator (nominal 10 kHz); an external capacitor to GND slows it down.
8 V+ power_in Positive power supply input, rated +1.5V to +10V, recommended to be bypassed to GND with a low ESR capacitor.
