TI - Three New Power Management Chips Increase Efficiency, Voltage and Output Current in LED Designs


Texas Instruments Incorporated (TI) introduced a high-power DC/DC boost LED driver (TPS61500) and high-voltage DC/DC boost converter (TPS61175), and expanded its step-down DC/DC converter series with TPS62110. These devices can support input voltages of up to 18-V and feature smaller voltage references for improved LED circuit design. These energy-efficient devices are cross-functional and work across a variety of LED applications, including signage, ambient light, office light, general illumination, military, medical and sensors.

  • Builds small, internal compensation and enables flexible configurations for different application needs like boost, SEPIC and fly back converters
  • Offers choice to design for efficiency, smallest solution size or specific frequency range

Key features of TPS62110

  • Adjustable input voltage: 3.1-V to 17-V
  • Adjustable output voltage: 1.2-V to 15-V
  • Maximum output current 1.5 A
  • Maximum efficiency 95 percent
  • Quiescent current: 20 uA; 2 uA in shutdown
  • Switching frequency: 1 MHz
  • Power good and low-battery detect
  • Soft start limits in-rush current

Key benefits of TPS62110

  • Closes the gap between low-power DC/DC converters for portable applications and higher power DC/DC SWIFTTM converters for industrial applications
  • As a LED driver new lighting achieves up to 90 percent in energy savings and the life time of the light increases up to 8 times
  • Can support fixed line rails like 12-V or 15-V, as well as a flexible number of battery cells
  • Small QFN package and small exterior inductor (6.8 uH) result in small overall solution size


The TPS61500, TPS61175 and TPS62110 are available now in production quantities.
