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).

This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Evaluation Kits (1)
The MAX18002 evaluation kit (EV kit) is a fully assembled and tested printed circuit board (PCB) that demonstrates the MAX18002 series of boost converters. The MAX18002 series has an input range of 0.5V to 5.5V, with a switch current limit of 3.6A and output voltage adjustable between 2.5V and 5.5V (ultrasonic mode (USM) and nanopower mode disabled for VOUT > 5V).
The EV kit can be ordered with MAX18000AWT+ (nanopower version) and MAX18002AWT+ (USM version). It is equipped with test points and jumpers for testing most of the functionality of the device. There are probing holes on critical nodes (OUT and LX) for precise measurements.
Features & Benefits
- 1.8V to 5.5V Input Voltage
- Test Points for INS, OUTS, and GNDS
- Sense Sockets at LX and OUT
- Output Voltage Adjustable Between 2.5V to 5.5V (in 100mV steps)
