Overview

High-efficiency step-down DC-DC converter is targeted for operation from 3.3V input voltage. It is able to supply circuits with programmable output voltage 1.8V at 0.7A output current. The DC-DC converter contains overvoltage protection, and undervoltage-lockout circuit. During startup time DC-DC converter can operate both in the soft start mode, which provides the gradual increase of the output voltage and without it. The embedded Bias and LDO blocks provide a required voltage and current references to DC-DC sub-blocks.

Breaking new energy efficiency records with advanced power management platform

The free lunch offered for decades by Moore’s law is now over and scaling down to the next technology node no longer offers the required energy efficiency gains. Design teams must now pursue their gains by deploying increasingly complex power management techniques to meet the demands of the new IoT markets.

Guide to Choosing the Best LDO for Your Application

To know which LDO you need, you must first define the application of your LDO and then examine which parameters are most important when dealing with that application. With the multiple parameters that characterize a particular LDO, it is not easy to determine which LDO is best suited. To help you figure this out, we have put together this reference. This guide presents a list of all the key LDO parameters along with their definitions, the most common applications of LDOs, and which parameters are critical for each.
