TPS61166DSKR Description

Short technical summary and product information.

The Texas Instruments TPS61166DSKR is a boost converter designed for driving white LEDs. It features an integrated 1.1-A / 20-V switch FET and power diode, capable of driving up to 5 LEDs in series.

 

This device supports an IC supply range of 2.5-V to 6-V and a power stage input range of 4.5-V to 10-V. It offers fast on/off LED current control within 1-µs, making it suitable for brightness dimming applications using a Burst PWM dimming method. The dimming frequency range is from 60-Hz to 40-kHz.

 

Key electrical specifications include a maximum switching frequency of 1.2 MHz (1400 kHz), a maximum duty cycle of 93%, and a peak efficiency of 85%. The operating temperature range is -40°C to 85°C.

 

The TPS61166DSKR is available in a compact 10-SON (2.5x2.5 mm) package with surface mount type. Its applications include small form factor LCD backlights, mobile phones, digital cameras, and personal camcorders.
