MAX17220‒MAX17225

400mV to 5.5V Input, nanoPower Synchronous

Boost Converter with True Shutdown

General Description

Beneﬁts and Features

● 300nA Quiescent Supply Current Into OUT

The MAX17220–MAX17225 is a family of ultra-low

quiescent current boost (step-up) DC-DC converters

with a 225mA/0.5A/1A peak inductor current limit and

True Shutdown™. True Shutdown disconnects the output

from the input with no forward or reverse current. The

output voltage is selectable using a single standard 1%

resistor. The 225mA (MAX17220), 500mA (MAX17222/

MAX17223), and 1A (MAX17224/MAX17225) peak inductor

current limits allow flexibility when choosing inductors. The

MAX17220/MAX17222/MAX17224 versions have post-

startup enable transient protection (ETP), allowing the

output to remain regulated for input voltages down to

400mV, depending on load current. The MAX17220–

MAX17225 offer ultra-low quiescent current, small total

solution size, and high efficiency throughout the entire load

range. The MAX17220–MAX17225 are ideal for battery

applications where long battery life is a must.
