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
