Product Details

The MAX17227J is a nanoPower boost converter capable of delivering a load up to 500mA peak inductor current and offering automatic pass-through operation, True Shutdown™, cycle-by-cycle inductor current limit, short-circuit, and thermal-protection features. The MAX17227J offers ultra-low quiescent current, small total solution size, and high efficiency throughout the load and line range. The MAX17227J is ideal for battery-powered applications where long battery life is a must and high efficiency is required at all power levels.

The MAX17227J utilizes an adaptive on-time, pulse-frequency-modulation (PFM) control scheme that consumes ultra-low quiescent current. The MAX17227J features True Shutdown mode, where the output disconnects from the input with no forward or reverse current. The active discharge resistor feature pulls the charge from the output capacitor.

The MAX17227J is offered in space-saving and cost-effective 1.58mm x 0.89mm, 6-bump WLP (3 x 2, 0.4mm pitch) and 2mm x 2mm, 8-pin TDFN packages. The operating temperature range is from -40°C to +125°C.
