MAX17220MAX17225 400mV to 5.5V Input, nanoPower Synchronous Boost Converter with True Shutdown General Description Benefits and Features The MAX17220MAX17225 is a family of ultra-low 300nA Quiescent Supply Current Into OUT quiescent current boost (step-up) DC-DC converters with True Shutdown Mode a 225mA/0.5A/1A peak inductor current limit and True 0.5nA Shutdown Current Shutdown. True Shutdown disconnects the output from Output Disconnects from Input the input with no forward or reverse current. The output No Reverse Current with V 0V to 5V OUT voltage is selectable using a single standard 1% resistor. 95% Peak Efficiency The 225mA (MAX17220/MAX17221), 500mA (MAX17222/ 400mV to 5.5V Input Range MAX17223), and 1A (MAX17224/MAX17225) peak inductor current limits allow flexibility when choosing inductors. The 0.88V Minimum Startup Voltage MAX17220/MAX17222/MAX17224 versions have post- 1.8V to 5V Output Voltage Range startup enable transient protection (ETP), allowing the 100mV/Step output to remain regulated for input voltages down to Single 1% Resistor Selectable Output 400mV, depending on load current. The MAX17220 225mA, 500mA, and 1A Peak Inductor Current Limit MAX17225 offer ultra-low quiescent current, small total MAX17220/MAX17221: 225mA I solution size, and high efficiency throughout the entire load LIM MAX17222/MAX17223: 500mA I range. The MAX17220MAX17225 are ideal for battery LIM MAX17224/MAX17225: 1A I applications where long battery life is a must.
