Key Features
- High-voltage boost regulation from 1.8 V to 6 V input up to 17 V output enabling white LED backlight strings
- 1.2 A peak switch current in a small DRV (SOT-563) package minimizing PCB footprint
- 1 MHz fixed switching frequency reducing inductor size and output ripple in portable designs
Applications
The TPS61170DRVR-S is designed to drive white LED backlight strings in small LCD displays for smartphones, portable media players, and handheld instruments. Its high output voltage capability up to 17 V makes it suitable for series LED strings requiring more than the battery voltage, while the compact SOT-563 package saves space on mobile device motherboards. The device also fits boost-rail applications in low-voltage portable systems needing a regulated 12 V or 15 V supply from a single Li-ion cell.

Frequently Asked Questions
What input and output voltage range does TPS61170DRVR-S support for LED backlight applications?
The TPS61170DRVR-S accepts an input voltage from 1.8 V to 6 V and regulates the boost output up to 17 V, enabling it to drive series white LED strings in LCD backlight circuits powered by single-cell Li-ion or two-cell alkaline batteries.
How does the 1 MHz switching frequency of TPS61170DRVR-S benefit portable device PCB layouts?
Operating at 1 MHz fixed switching frequency allows the use of a small 2.2 µH to 4.7 µH inductor and compact ceramic output capacitors, reducing the total power stage footprint to under 10 mm² on smartphone and tablet PCBs.
For a 4-LED series backlight string at 3.3 V forward voltage each, can TPS61170DRVR-S supply sufficient output?
Yes. Four white LEDs with 3.3 V forward voltage each require approximately 13.2 V total; the TPS61170DRVR-S maximum output of 17 V comfortably accommodates this string voltage plus headroom, with 1.2 A peak switch current supporting brightness adjustment via PWM dimming.
What package does TPS61170DRVR-S use, and how does it compare to WSON or SOT-23 alternatives?
The TPS61170DRVR-S uses a DRV (SOT-563) 6-pin package measuring approximately 1.6 mm × 1.6 mm, which is smaller than the SOT-23-5 footprint but provides comparable thermal dissipation for output powers up to 1 W in typical LED driver applications.
