TPS61178RNWR General Description
The TPS61178RNWR is a step-up DC/DC converter from Texas Instruments designed for driving white LEDs in backlighting applications. It operates with an input voltage range of 2.7V to 18V, making it suitable for various power sources, including single-cell Li-ion batteries and multi-cell alkaline or NiMH batteries. This device incorporates a high-efficiency boost converter with a 1.2A switch current capability, enabling it to drive multiple LEDs in series. With a fixed-frequency PWM control scheme, it ensures stable and flicker-free operation.The TPS61178RNWR offers a wide dimming range through pulse width modulation (PWM), allowing precise control of LED brightness to meet different application requirements. It features built-in overvoltage protection, overcurrent protection, and thermal shutdown to safeguard both the device and the LEDs from potential damage under fault conditions. The device is housed in a compact, thermally-enhanced WQFN package, facilitating easy integration into space-constrained designs while ensuring efficient heat dissipation.
