General Description

The MAX18000 is a nanoPower 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 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 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 700mA 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).
