The TPS61183RTJR from Texas Instruments is an active WLED driver IC designed for notebook applications. It offers a PWM interface for programmable brightness control, enabling precise dimming ratios up to 10000:1. The device supports an input voltage range of 4.5V to 24V and can deliver an output voltage of up to 40V.
This LED driver features six current sinks, each capable of delivering 30mA with a typical current matching of 1.5%. It operates with a programmable switching frequency between 280kHz and 1MHz, and a maximum duty cycle of 94%. The device includes integrated loop compensation and protection features such as WLED open and short protection, and thermal shutdown.
The TPS61183RTJR is available in a 20-WFQFN exposed pad package, measuring 4mm x 4mm, and is designed for surface mounting. Its operating temperature range is -40°C to 85°C, making it suitable for various environmental conditions. The driver also incorporates 4000V HBM ESD protection.
