TPS61170DRVR Power Management IC For High-Efficiency LED Lighting Solutions

TPS61170DRVR LED Driver IC 

Description: 

The TPS61170DRVR is a high efficiency, low-voltage, constant-current LED driver specifically designed to drive high-brightness LEDs (HB-LEDs) in mobile applications. It operates with a wide input voltage range of 2.7 V to 5.5 V and is capable of delivering up to 20 mA of output current. It features a built-in boost converter, which provides the highest efficiency when driving HB-LEDs. The device also offers a wide range of features, such as programmable output current, low quiescent current, low shutdown current, and low output ripple current. Additionally, an optional low-power shutdown mode is available for ultra-low power applications.
