Part details & applications

The MAX18000 is a nanoPower boost converter with an input voltage range of 0.5V to 5.5V (V_OUT > V_IN + 0.2V) and a switching current limit of 3.6A. It features an ultralow quiescent current of 512nA which makes it ideal for battery-powered applications requiring a long standby time. The IC operates in nanoPower 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 R_SEL resistor.

The IC features a True Shutdown™ mode, which disconnects V_IN and V_OUT when the EN pin is pulled low. It also features short-circuit protection circuitry that limits the current to 700mA when V_OUT < 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).
