Overview
Datasheet ISL9122A Ultra-Low IQ Buck-Boost Regulator With Bypass The ISL9122A is a highly integrated non-inverting buck-boost switching regulator that accepts input voltages both above or below the regulated output voltage.
It features an extremely low quiescent current consumption of 1300nA in Regulation mode, 120nA in Forced Bypass mode, and 8nA in Shutdown mode.
It provides 84% efficiency at 10µA load (VIN = 3.
6V, VOUT = 3.
3V) and has peak efficiency greater than 97% (VIN = 3.
6V, VOUT = 3.
3V).
It supports input voltages from 1.
8V to 5.
5V.
The ISL9122A has automatic bypass functionality for situations in which the input voltage is close to the output voltage, and it automatically transitions between Buck and Boost modes without significant output disturbance.
In addition to the automatic bypass functionality, the Forced Bypass power saving mode can be chosen if voltage regulation is not required.
Forced Bypass power saving mode is accessible using the I2C interface bus.
