The AL3353S-13 from Diodes Incorporated is a cost-effective LED controller designed for LCD monitor and TV backlighting applications. This device provides a high-performance LED backlight solution with a low Bill of Materials (BOM) cost.
It features a current mode PWM boost driver with fixed frequency operation, regulating LED current through an external sense resistor. The AL3353S-13 supports both PWM and analog dimming modes for wide-ranging control. Key electrical specifications include a wide input voltage range of 9V to 40V and a high precision feedback reference voltage of 400mV with ±1.5% tolerance. The switching frequency is 130kHz.
Comprehensive protection features are built-in, including Undervoltage Lockout (UVLO), Output Overvoltage Protection (OVP), Power MOSFET Overcurrent Protection (OCP), Diode and Inductor Short Protection, LED Cathode Short to GND Protection, LED Open Protection, VOUT Short Protection, and Overtemperature Protection (OTP).
The AL3353S-13 is available in a Pb-Free SO-8 package (Type TH2) suitable for surface mounting. It is designed for applications such as LCD TVs, LCD Monitors, and Flat Panel Displays.
