Price:
£2.13 GBP

Description

This DC/DC step-down voltage converter's input voltage between 4.5V and 28V into a smaller voltage between 0.8V and 18V, capable of driving a 3A load with excellent line and load regulation.

Note: Input must be >1.5V higher than output! The chip will get to high-temperature protection mode when it works at a high-power conversion, without any cooling, it is able to output 3A current at 5V. But at higher output voltage, the current output capacity is lower than 3A, approx 2A.

Features

Wide 4.5V to 28V Operating Input Range
Up to 92% Efficiency
Programmable Switching Frequency from 100kHz to 1.5MHz
High-Efficiency Pulse Skipping Mode for Ceramic Capacitor Stable
Internally Set Current Limit without a Current Sensing Resistor
Cycle-by-Cycle Over Current Protection
