The IS31LT3948-GRLS2-TR from Lumissil Microsystems is a PFM step-up DC-DC converter specifically engineered for large-size LCD panel backlighting. This device is capable of delivering stable constant output current up to 2A, which can be programmed using an external resistor.
It features a wide input voltage range from 5V to 100V, making it suitable for various applications. The converter utilizes an efficient control scheme that automatically adjusts the output voltage to optimize system efficiency and is inherently stable, eliminating the need for external loop compensation. The IS31LT3948 also supports external PWM dimming for flexible control of backlighting luminance.
Integrated over-voltage protection (OVP) and over-temperature protection (OTP) are included to safeguard the chip and the system, even under no-load conditions. The device is housed in a compact SOP-8 package and operates across two temperature ranges: -40°C to +85°C and -40°C to +125°C.
Applications for the IS31LT3948-GRLS2-TR include TV monitor backlighting, notebooks, automotive systems, street lamps, and general LED lighting.
