Overview

Description

TPS61199PWPR is Texas Instruments’ constant-current LED driver IC. It uses a switching regulator to drive LEDs from a wide input voltage (battery or supply) with an external inductor and sense resistor to set the current. Key features typically include adjustable LED current, PWM dimming control, and protection functions such as LED open/short-circuit, overcurrent, and thermal shutdown. It is designed for LED backlighting, indicators, and flash/automotive lighting, where stable current and good efficiency are important. The PWPR suffix means Pb-free packaging in tape-and-reel. For exact electrical specs and external components, refer to the TPS61199 datasheet.

Features

Here are the typical features of the TPS61199PWPR:
- 1-A constant-current LED driver with a buck-boost switching regulator (suitable for single-cell or USB sources)
- Wide input voltage range (designed for Li‑ion/USB-like supplies)
- Adjustable/programmable LED current via feedback resistor
- Dimming: PWM and/or DC dimming options
- High efficiency with low quiescent current
- Protection features: overcurrent/short-circuit protection, thermal shutdown, undervoltage lockout
- Soft-start to reduce inrush and LED current overshoot
- Enable/shutdown control for power saving
- Small 8-pin PWPR package (compact footprint)
Note: For exact electrical specifications (values, tolerances, and pinouts), refer to the official datasheet.

Package

TPS61199PWPR uses a WSON-8 package (3×3 mm) with an exposed pad.

Pinout

TPS61199PWPR is an 8-pin PWPR (WSON-8) package LED driver. It is a one-channel boost converter that provides constant-current drive to a LED string.
Pin/function overview (grouped):
- VIN/GND: power supply input and ground.
- LX (SW): switching node connected to the inductor.
- LED: output to the LED string.
- ISET: sets the LED current via a programming resistor.
- FB: feedback node for current regulation.
- EN: enable/shutdown control.
- Exposed Pad (EP): thermal/ground reference (connected to ground).
In short: 8 pins in PWPR; single-channel boost LED driver with input, switch node, LED output, current-setting, feedback, and enable pins (plus an exposed pad for heat dissipation).

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits, sensors, and related electronics; headquartered in Dallas, Texas, and one of the world’s largest semiconductor producers.

Application

TPS61199PWPR application areas:
- White LED backlight driver for LCDs in mobile devices, tablets, notebooks, and automotive displays (constant-current)
- Battery-powered devices requiring efficient buck/boost regulation from Li‑ion sources (smartphones, wearables, cameras)
- General compact DC-DC power management in portable electronics
- LED lighting applications (industrial/automotive) needing high efficiency in a small footprint
