MAX18000 Datasheet | Analog Devices

Description The MAX18000 is a nano Power boost converter with an input voltage range of 0.5V to 5.5V (VOUT > VIN + 0.2V) and a switching current limit of 3.6A. It features an ultralow quiescent current of 512n A which makes it ideal for battery-powered applications requiring a long standby time. The IC operates in nano Power mode at low loads and transitions into skip and CCM modes of operation at higher load currents to ensure high efficiency over a wide current range. The output voltage can be varied between 2.5V and 5.5V using a single RSEL resistor. The IC features a True Shutdown™ mode, which disconnects VIN and VOUT when the EN pin is pulled low. It also features short-circuit protection circuitry that limits the current to 700m A when VOUT < 0.5V and automatically restarts the part when the fault is removed. The thermal-shutdown protection disables the part when the junction temperature crosses +165°C (typ). The IC is available in 1.07mm x 1.57mm, 6-bump waferlevel package (WLP).
