A8504952140A - Brand New Amphenol PCD Backshells and Cable Clamps
-
Description
The A8504952140A is a multi-output WLED driver for medium display backlighting in the category of backshells and cable clamps. It integrates a boost converter and eight current-sinks to provide a WLED/RGB backlight driver. As a result, this driver can provide output voltage up to 47 V. Its flexible channel selection control and high-voltage capability allow a wide range of LED backlight applications, including thin notebook displays, LCD TVs, RGB backlights, GPS systems, and portable DVD players.
Specifications and features
The A8504952140A LED driver is designed with active current sharing between 6 LED strings for ±1.3% typical current and ±1.2% typical current accuracy. This LED driver can also drive up to 11 series × 8 parallel = 88 LEDs (Vf = 3.5 V, If = 40 mA). It features external PWM control for LED dimming, an external resistor for LED current setting, and a boost converter with an integrated 50 V, 2 A DMOS. Its LED sinks are rated for 45 mA, and it has a switching frequency range of 200 kHz to 2 MHz. Additionally, it has an open LED disconnect, boost current limit, thermal shutdown, and soft start. There is no audible ceramic capacitor noise during PWM dimming, and it has adjustable overvoltage protection (OVP). No pull-up resistors are required for LED modules that use ESD capacitors.
Application Scenarios
The A8504952140A LED driver is versatile and can be used in various LED backlight applications, including thin notebook displays, LCD TVs, RGB backlights, GPS systems, and portable DVD players. It is particularly suitable for medium display backlights where the voltage requirement ranges up to 47V.
