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.
Features:
• Input voltage range: 2.7 V to 5.5 V
• Output current up to 20 mA
• Programmable output current
• Low quiescent current
• Low shutdown current
• Low output ripple current
• Optional low-power shutdown mode
• High efficiency boost converter
• Accurate current regulation
• Internal current-limit protection
• Thermal shutdown protection
