MAX18000AWT+T

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 ShutdownTM 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 × 1.57mm 6- bump waferlevel package (WLP).
