TPS92691 - Multi-Topology LED Driver

General Description

The TPS92691/-Q1 is a versatile LED controller that can support a range of step-up or step-down driver topologies.

The device implements a fixed-frequency peak current mode control technique with programmable switching frequency, slope compensation, and soft-start timing.

Key Features

  • 1 Wide Input Voltage: 4.5 V to 65 V.
  • Wide Output Voltage Range: 2 V to 65 V.
  • Low Input Offset Rail-to-Rail Current Sense Amplifier.
  • Better than ±3% LED Current Accuracy over 25°C to 140°C Junction Temperature Range.
  • Compatible With High-Side and Low-Side Current Sense Implementations.
  • High-Impedance Analog LED Current Adjust Input (IADJ) With over 15:1 Contrast Ratio.
  • Over 1000:1 Series FET PWM Dimming Ratio With Integrated Series N-.
