MAX17227A 400mV to 5.5V Input, 2A nanoPower Boost Converter with Short-Circuit Protection and True Shutdown General Description Benefits and Features The MAX17227A is a nanoPower boost converter capable 350nA Quiescent Supply Current from Output of delivering load up to 2A peak inductor current and offer- Output Short-Circuit Protection ing True Shutdown, cycle-by-cycle inductor current lim- True Shutdown Mode it, short-circuit, and thermal protection. During shutdown, 1nA Shutdown Current current drawn from the input pin is 1nA. The MAX17227A Output Disconnects from Input offers ultra-low quiescent current, small total solution size, No Reverse-Current with Any Voltage on V OUT and high efficiency throughout the load and line range. 96% Peak Efficiency, 90% or Higher at 500A The MAX17227A is ideal for battery-powered applications Typical 850mA Output Current at 5.0V (V = 3.0V) IN where long battery life is a must and high efficiency is re- 400mV to 5.5V Input Range, Up to 5.35V in quired at all power levels. Regulation The MAX17227A utilizes adjustable on-time, pulse-fre- 880mV Minimum Startup Voltage quency-modulation (PFM) control scheme that consumes Single Resistor-Adjustable Output Voltage ultra-low quiescent current. The MAX17227A features 2.3V to 5.2V Output Voltage Range with 100mV True Shutdown mode where the output disconnects from Steps the input with no forward or reverse-current. This saves 5.5V Output Voltage Setting Available precious energy from the battery for systems that dynam- 2A Peak Inductor Current Limit ically turn on and off by having the ability to startup into a Thermal Shutdown Protection precharged output capacitor. Multiple Package Options The MAX17227A is offered in a space-saving and cost- 1.58mm x 0.89mm, 0.4mm Pitch, 6-Bump (3 x 2) effective 1.58mm x 0.89mm, 6-bump WLP (3 x 2, 0.4mm WLP pitch) and 8-pin, 2mm x 2mm TDFN packages. The oper- 2mm x 2mm, 8-Pin TDFN ating temperature range is from -40C to +125C. -40C to +125C Operating Temperature Range Applications Ordering Information appears at end of data sheet.
