Product Description

ADI chips MAX38888ATD+T 2.5V to 5.0V, 0.5A/2.5A Reversible Buck/Boost Regulator for Backup Power Applications

General Description

The MAX38888 is a storage capacitor or capacitor bank

backup regulator designed to efficiently transfer power be-

tween a storage element and a system supply rail in re-

versible buck and boost operations using the same induc-

tor.

When the main supply is present and above the minimum

system supply voltage, the regulator operates in buck

mode and charges the storage element at up to 500mA

peak inductor current. Once the storage element is

charged, the circuit draws only 2.5µA of current while it

maintains the supercapacitor or other storage element in

its ready state. When the main supply is removed, the reg-

ulator operates in boost mode and prevents the system

from dropping below the minimum operating voltage, dis-

charging the storage element at up to 2.5A peak inductor

current.

The MAX38888 is externally programmable for minimum

and maximum voltage of the storage element, such as

supercapacitor, minimum system voltage, and maximum

charge and discharge currents. The internal DC-DC con-

verter requires only a 1µH inductor.
