OZ813
Overview
OZ813 is a DC/DC controller specially developed to design power supplies for next generation microprocessors, their peripherals and chipsets. OZ813 steps down the high battery voltage to low output voltages in the range of 0.5V to 2.75V.
- Dual DC-DC SMPS controller with integrated drivers Two constant ripple-current controllers Constant ripple-current control allows optimum inductor size High full load efficiency; up to 94% High light load efficiency; >85% at 100mA Vout accuracy; 1% or better Input voltage; from 3V to 26V Output voltage - adj. from 0.5V to 2.75V Output current - up to 15A Independent o Power Good signals o ON/SKIP signals Soft-Start at start-up Soft-stop at shutdown Voltage Feed-Forward Compensation User adjustable operating frequency Dynamic voltage change support Output Protection: o Latched Over Voltage Protection o Latched Under Voltage Protection o Valley type Over Current Protection Input Protection: o Under Voltage Lock Out on VDDA o Under Voltage Lock Out on VIN
