TC7662BCPA

Microchip Tech · DC-DC Converters · PDIP-8

TC7662BCPA from Microchip Tech, in a PDIP-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 by approximately 3-1/2 times, while leaving it open or at GND keeps the nominal 10kHz oscillator.
2 CAP+ passive Positive terminal of pump capacitor C1; when polarized capacitors are used in the inverting mode, the + terminal of C1 must connect to this pin.
3 GND power_in Ground reference; when polarized capacitors are used in the inverting mode, the - terminal of C2 must connect to GND.
4 CAP- passive Negative-side pump capacitor connection (C1) of the charge pump, as shown in the test circuit.
5 VOUT power_out Converter output, which is -V+ in the simple negative converter; shorting the output to V+ above 5.5V is allowed only for transient conditions.
6 LV input Connect to GND to disable the internal regulator for supplies up to 3.5V; for supplies above 3.5V this pin must be left open, and current into LV is limited to 20µA when V+ is above 3.5V.
7 OSC input Oscillator timing node; connecting an external capacitor from OSC to ground with pin 1 open lowers the oscillator frequency below 10kHz.
8 V+ power_in Positive supply input, rated 1.5V to 15V in operation with a 16.5V absolute maximum supply voltage.
