Charge pump for low-power positive rails
The MAX1730EUB+: Switching at 2 kHz, it generates a regulated 1.8 V or 1.9 V output without a synchronous rectifier — the charge-pump topology keeps the BOM lean for low-current auxiliary rails.
The 50 mA output ceiling suits it for powering a small MCU, an op-amp rail, or a reference buffer — not a main power bus. Programmable output via a logic pin selects 1.8 V or 1.9 V — useful when the same PCB must serve two core-voltage targets without a resistor swap.
Active production and compliance
Supplied in tubes, the 10-uMAX/uSOP footprint matches the standard 10-MSOP land pattern; the 0.118-inch body width fits tight channel spacing on a mixed-signal board.
