The MAX18002 is an ultrasonic, high-performance boost converter with an input voltage range of 0.5V to 5.5V and a switching current limit of 3.6A. The IC operates in ultrasonic mode (USM) (FSW at 29kHz typ) at low loads and transitions into skip mode and continuous conduction mode (CCM) of operation at higher load currents. The MAX18002 can operate in pass-through mode when the input voltage is higher than the output voltage.
The output voltage can be varied between 2.5V and 5.5V (USM disabled for VOUT > 5V) using a single RSEL resistor.
The MAX18002 features a True Shutdown™ mode which disconnects VIN and VOUT when the EN pin is pulled low. It also features a 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 MAX18002 is available in 1.07mm x 1.57mm, 6- bump, wafer-level package (WLP).
