Overview

Description
The AOZ1051PI is a high-efficiency, easy-to-use, 3 A synchronous buck regulator. It operates within an input voltage range of 4.5 V to 18 V and delivers up to 3 A of continuous output current. The output voltage is adjustable down to 0.8 V. The AOZ1051PI is packaged in an exposed pad SO-8 and operates over a temperature range of -40 °C to 85 °C.

Features
Input voltage range: 4.5 V to 18 V
Synchronous buck design with 70 mΩ internal high-side switch and 40 mΩ internal low-side switch (at 12 V)
Up to 95% efficiency
External soft start
Output voltage adjustable to 0.8 V
3 A continuous output current
500 kHz PWM operation
Cycle-by-cycle current limit
Pre-bias start-up
Short-circuit protection
Thermal shutdown
Exposed pad SO-8 package

Applications
Point of load DC/DC converters
LCD TVs
Set top boxes
DVD and Blu-ray players/recorders
Cable modems
