Texas InstrumentsTPS61150EVM-150

The TPS61150EVM-150 is an evaluation tool for the TPS6115x family. This is a dual channel, single Inductor Boost Converter with two regulated current outputs for driving white LEDs. Each current output can be individually programmed through external resistors and is capable to drive 6 to 7 white LEDs (3.5 V or 4 V forward voltage) up to a total of 12 or 14 LEDs.

• Input Voltage: 3 V to 6 V
• Output Voltage: up to 27 V each (max)
• Switch current Limit: 0.7 A (max)
• Efficiency: 83% (max)
• 2 Individual programmable, regulated current Outputs
• Built in Power Diode and Soft-start
• Input to Output isolation
• Over voltage and Short circuit protection
• Built in 1.2 MHz fixed switching frequency
• Up to 30 kHz dimming frequency
• Package: 3x3 QFN-10
