MAX8790 Overview
Key Specifications
Mount Type: Surface Mount
Pins: 20
Max Voltage (typical range): 26 V
Min Voltage (typical range): 4.5 V
Description
The MAX8790 is a high-efficiency driver for white lightemitting diodes (LEDs). It is designed for large liquidcrystal displays (LCDs) that employ an array of LEDs as the light source.
Key Features
- to protect the controller from fault conditions
- Separate feedback loops limit the output voltage if one or more LEDs fail open or short
- The controller features cycle-by-cycle current limit to provide consistent operation and soft-start capability
- A thermal-shutdown circuit provides another level of protection
- Low feedback voltage at each LED string (450mV) helps reduce power loss
