Brief Description

The KTB8331 is a precision adaptive-on-time (AOT)

buck switching regulator with class-leading accuracy,

transient response, efficiency, and solution size

optimized for mobile and non-mobile application. It is

I2C programmable for output voltages in the 0.6V to

3.345V range. It features soft-start and DVS with

multiple programmable ramp rates. Versions with

various default settings can be ordered. The features

and performance make the KTB8331 suitable for a

variety of applications including CPU/GPU core, DSP

and baseband, DDR memory, VIO, and sensor/analog

power.

The KTB8331 is available in RoHS and Green

compliant 15-bump 1.340mm x 2.045mm x 0.6mm

wafer-level chip-scale package (WLCSP).
