# TPS61187 (Component) ## Description The Texas Instruments TPS61187 is a highly integrated white-light-emitting-diode (WLED) driver tailored for notebook LCD backlight applications. Operating over an input voltage range of 4.5 V to 24 V, this component integrates a 2-A, 40-V MOSFET in its design, offering a maximum output voltage of 38 V. It provides up to six current sinks capable of supplying a maximum of 30 mA each, accommodating up to 60 WLEDs in total. The TPS61187 supports both automatic phase-shift dimming and direct PWM dimming methods, allowing for versatile control over the backlight brightness with dimming ratios reaching 100:1 at 20 kHz and 10000:1 at 200 Hz in direct PWM mode. Programmability extends to its switching frequency, which can be set from 300 kHz to 1 MHz, facilitating optimization for efficiency and performance. This component also incorporates protection features against overvoltage, open/short WLED conditions, and thermal shutdown, ensuring reliable and safe operation in demanding notebook backlighting scenarios. ## Component Details - **Owner:** cd99 - **Created:** 5/14/2024 - **Last Updated:** 5/14/2024 - **Visibility:** Public - **Manufacturer Name:** Texas Instruments None - **Datasheet URL:** https://cdn2.flux.ai/copilot-datasheets/pdf-upload-77db29c8822303558eec9d665eac908eb094e3e3dc5d85a0218273149babfd5c/6b5bda141e71f11dd09c2ac2cf61a2486bc158cd657dc24038acd47916bf8f93.pdf?GoogleAccessId=graviton-mvp%40appspot.gserviceaccount.com&Expires=4869314903&Signature=BVj8Q35kE6OoxLS2vXIb606vQAg%2BCAW%2Bp645Go4%2B7j35rj5Z%2FRGm5OKimZyD58zIe%2BpV6B0XWEJgPC797%2FACW5YOSZbXUfv%2BhK6D1F%2BLBhEojAs35sFlR9vDcuXD79wctjthKDKep1wBBJqfZOUQR6%2B0gg7nml%2FIXjJZ3NNzrq4jCpVBe97ylFNBJdQDnDb9KpemMbY7w2ELCGSb2ZLP2ROuzmH0MslPt3NIfLhNBIzohDQiSyz7sYgAVrpB7HOQ1bqKAnK2EDIyPnoTs0bDJlok8py2h9KPd9d4tDgjgH537p0jlA4HSeaxGAfzr9wl6gf1yW1I92JIAwu1E8X3lQ%3D%3D - **Materials:** 150 None - **Manufacturer Part Number:** TPS61187RTJR None - **Package or Case Code:** QFN65P500X500X80-21WN - **Part Type:** Regulator - **License:** https://creativecommons.org/licenses/by/4.0/ - **Compliance:** UL, CE, RoHS None - **Used in:** 2 projects - **Part Type:** Other - **Manufacturer:** Texas Instruments - **MPN:** TPS61187RTJR None - **Package / Case Code:** QFN - **Pin Count:** 21 - **Compliance:** Rohs, REACH ## Pins | Pin | Name | Type | |-----|------|------| | 1 | VDDIO | | | 2 | EN | | | 3 | FSLCT | | | 4 | ISET | | | 5 | FPO | | | 6 | IFB6 | | | 7 | IFB5 | | | 8 | IFB4 | | | 9 | GND | | | 10 | IFB3 | | | 11 | IFB2 | | | 12 | IFB1 | | | 13 | RFPWM/MODE | | | 14 | OVC | | | 15 | PGND | | | 16 | SW | | | 17 | NC | | | 18 | FAULT | | | 19 | VIN | | | 20 | PWM | | | 21 | Thermal Pad | | --- *Generated from [https://www.flux.ai/cd99/tps61187~qy](https://www.flux.ai/cd99/tps61187~qy)*
