Product details

Ratiometric charge pump — Vout tracks Vin at 2×

The MAX1682EUK: Its ratiometric topology means the output voltage is fixed at twice the input voltage.

45 mA output — what it drives and what it doesn't

Rated for 45 mA continuous output, this part suits low-current rails. The single positive output is unregulated — the output voltage is Vin × 2 minus the diode drops and switch losses.

SOT-23-5 footprint and temperature grade

Housed in a 5-pin SOT-23-5 surface-mount package.

RoHS status is noted as non-compliant — verify your assembly's exemption or lead-free policy.

Frequently asked questions

Does MAX1682EUK require external capacitors?

Yes — as a switched-capacitor charge pump it needs two external capacitors: one flying capacitor between the C+ and C- pins, and one output storage capacitor from Vout to ground. Typical values are 1 µF to 10 µF ceramic. The datasheet provides the recommended values for the target load current.
