TC7662BEOA713

Microchip Tech · DC-DC Converters · SOIC-8

TC7662BEOA713 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 BOOST input Connecting this pin to V+ raises the oscillator frequency from the nominal 10 kHz to about 35 kHz, while leaving it open or at GND keeps the nominal frequency.
2 CAP+ passive Positive terminal of pump capacitor C1; when polarized capacitors are used in the inverting mode, the + terminal of C1 must be connected to this pin.
3 GND power_in Ground reference for the device; the LV pin is tied to this node for supply voltages below 3.5 V, and the negative terminal of C2 must be connected here when polarized capacitors are used in the inverting mode.
4 CAP- passive Negative terminal of pump capacitor C1, which the device shifts negatively by V+ volts during the second half of each cycle.
5 VOUT power_out Negative output, VOUT = -VIN for the standard inverting connection; the output must not be shorted to V+ for extended periods when the supply exceeds 5.5 V (transient and start-up conditions are allowed).
6 LV input Low-voltage pin that must be connected to GND for supply voltages below 3.5 V to disable the internal regulator, and must be left open for supplies above 3.5 V; current into LV is limited to 20 µA when V+ is above 3.5 V.
7 OSC passive Oscillator timing node where an external capacitor to ground (with pin 1 open) lowers the oscillator frequency below 10 kHz, with the pump and reservoir capacitors scaled up by the same factor.
8 V+ power_in Positive supply input, specified at 3.0 V to 15 V with LV open or 1.5 V to 3.5 V with LV tied to GND, with an absolute maximum of 16.5 V.
