It delivers up to 30 mA at a fixed switching frequency of 200 kHz. The part comes in a 6-lead SC-70-6 surface-mount package and operates over the -40°C to 85°C industrial temperature range. Typical applications include generating a small negative bias rail for op-amps, LCD contrast supplies, or a low-current boosted rail in battery-powered portable gear. ## 30 mA output — sizing the load budget The 30 mA output current limit is the hard ceiling for this charge pump. It suits small-signal rails — a single op-amp bias, a level-shifter supply, or an LCD contrast driver — not a main power rail. If your load draws more than 30 mA peak, this part will drop out of regulation. The fixed 200 kHz switching frequency means the output ripple spectrum is predictable; plan for a ceramic output capacitor sized for that frequency. ## Input range and output configuration Input voltage spans 2.5 V to 5.5 V. The output is ratiometric, not regulated — it tracks the input as either -Vin or 2Vin. ## Active lifecycle, no obsolescence concern The MAX1853EXT+T carries an active product status. For new designs or BOM replenishment, the part is available through independent distribution channels and is quoted to order against an RFQ.","metaTitle":"MAX1853EXT+T Charge Pump IC, 30 mA, SC-70-6","metaDescription":"MAX1853EXT+T charge pump IC from Analog Devices.
