Overview
| Topology | Buck Converter |
| Input voltage | 5-55 V |
| Output 1 | 1 A |
Description
The AL8862QEV1, Figure 1, is a double sided evaluation board for the AL8862Q step-down, or ‘buck’, LED driver with internal switch in the SO-8EP package. The evaluation board is preset to drive1000mA into a single LED, or multiple LEDs, the maximum number of which depends on their total forward voltage drop and the supply voltage. (The maximum drive current of the AL8862Q is 1000mA)
Features
- Wide Input Voltage Range: 5V to 55V
- Output Current up to 1A
- Brightness control using DC or PWM.
- High Efficiency (Up to 97%)
- Fault Status Indication for Abnormal Operation
- LED Short-Circuit Protection
- Inherent Open-Circuit LED Protection
- Current-Sense Resistor Short-Circuit Protection
- Over Temperature Shutdown
- Up to 1MHz Switching Frequency
Typical applications
- Automotive Interior LED Lamps, Automotive Exterior LED Lamps
