Alpha & Omega Semiconductor AOZ1948AI

Single Channel HV LED Driver IC ,Advanced Evaluation Board (subject to change)

Overview

TopologyBuck Converter
Input voltage120 V
Output 10.25 A

Description

The AOZ1948 evaluation board is a fully assembled and tested circuit board built with the AOZ1948 Buck regulator IC. It’s output is preset to drive 100V LED at 250mA of continuous or PWMed current. The evaluation board will operate from input voltage range from 115V to 190V.The AOZ1948-EVA circuit has features like current limit, short circuit protection, shorted LED and thermal shut down. It is an Off-Time controller that operates in Fully continuous conduction mode CCM for improved efficiency and low 1% dimming, it requires minimal amount of external components The AOZ1948 comes in SO-8 package and is rated over a -40°C to +85°C ambient temperature range.
