Product Details
The Maxim Integrated Buck/Boost regulator has 2.5V to 5.5V system output voltage range. The MAX38889 is a flexible storage capacitor or capacitor bank backup regulator transferring power efficiently between a storage element and a system supply rail. The main supply is present and its voltage is above the minimum threshold system supply voltage, the regulator operates in charging mode and charges the storage element with a maximum 3A peak, 1.5A average inductor current.
2.5V to 5.5V system output voltage range
0.5V to 5.5V supercapacitor voltage range
±1% threshold accuracy
2.5% Hysteresis between backup and charging
0.5V to 5.5V supercapacitor voltage range
