No synchronous rectifier is integrated — the output diode is external. A Schottky with low Vf (e.g., 0.3 V at 100 mA) keeps conduction loss in check; the charge pump's output impedance rises with the diode drop, so the diode choice directly affects the available load current at the regulation point. ## Package and thermal: 6-DFN with exposed pad The supplier device package is 6-DFN (2x2), so the stencil aperture for the centre pad should match the datasheet recommendation to avoid voids under the die attach pad. ## Temperature grade and operating range The input minimum of 1.8 V means the part starts from a nearly depleted Li-Ion cell (3.0 V nominal, down to 2.7 V cutoff) or two alkaline cells at end-of-life (1.0 V each under load). The 4.4 V maximum input limits it to single-cell Li-Ion or 2-3 cell alkaline/NiMH — not a 5 V rail.","metaTitle":"LTC3221EDC-3.3#TRMPBF Charge Pump, 60 mA, 3.3 V Fixed","metaDescription":"LTC3221EDC-3.3#TRMPBF active-production charge pump step-up regulator from Analog Devices. 60 mA output, 3.3 V fixed, 600 kHz, 6-DFN.
