MAX38640/1/2/3 Tiny 1.8V–5.5V Input, 330nA IQ, 700mA nanoPower Buck Converter General Description Benefits and Features The MAX38640/1/2/3 are nanoPower family of ultra-low 330nA quiescent current buck (step-down) DC-DC converters operating from 1.8V to 5.5V input voltage and supporting load currents of up to 175mA, 350mA, 700mA with peak efficiencies of 96%. While in shutdown, there is only 5nA of shutdown current. The devices offer ultra-low quiescent current, small total solution size, and high efficiency throughout the load range. The MAX38640/1/2/3 are ideal for battery applications where long battery life is a must. ● Extends Battery Life • 330nA Ultra-Low Quiescent Supply Current • 5nA Shutdown Current • 96% Peak Efficiency and Over 88% at 10µA ● Easy to Use – Addresses Popular Operation • 1.8V to 5.5V Input Range • Single Resistor Adjustable VOUT from 0.7V to 3.3V (A-Option) • Preprogrammed VOUT from 0.5V to 5.0V (B-Option) • ±1.75% Output Voltage Accuracy • Up to 175mA/350mA/700mA Load Current The MAX38640/1/2/3 family utilizes a unique control scheme that allows ultra-low quiescent current and high efficiency over a wide output current range. MAX38642 excludes active discharge resistor in shutdown which allows the output to be regulated or held high by another source or by the charged output capacitor. ● Protects System in Multiple Use Cases • Reverse-Current Blocking in Shutdown • Optional Active Discharge Feature ● Reduces Size and Increases Reliability • -40°C to +85°C Temperature Range • 2mm x 2mm 6-pin µDFN Package • 1.42mm x 0.89mm, 0.4mm Pitch 6-pin (2 x 3) WLP The MAX38640/1/2/3 devices are offered in a space-saving 1.42mm x 0.89mm, 6-pin WLP (2 x 3 bumps, 0.4mm pitch), as well as a 2mm x 2mm, 6-pin µDFN package. All parts are specified from -40°C to +85°C. Ordering Information appears at end of data sheet. Applications ● Portable Space-Constrained Consumer Products ● Wearable devices, Ultra-Low-Power IoT, NB IoT, and BLE ● Single Li-ion and Coin Cell Battery Products ● Wired, Wireless, Industrial Products Typical Operating Circuit 2.2µH INPUT 1.8V-5.5V IN LX OUT CIN OUTPUT 1.8V COUT 10µF 22µ F MAX38640A RSEL EN 19-100410; Rev 2; 5/19 GND RSEL 768kΩ PDF
