TS1916 - 1.7A Boost WLED Driver

Description

The TS1916 is a step-up (Boost) converter designed for driving up to 10 series white LEDs for backlighting application.

The TS1916 uses current mode, 1MHz fixed frequency architecture to regulate the LED current, which is set through an external current sense resistor.

Features

  • 2.5V to 5.5V operating input voltage range.
  • Drives up to 10 series white LEDs.
  • 1MHz fixed switching frequency.
  • Wide range for PWM dimming (200Hz to 200kHz).
  • Internal 1.7A switching current limit.
  • Over voltage protection (OVP).
  • Internal soft-start function.
  • Current limit and thermal shutdown protection.
  • Under voltage lockout.

TS1916 1.7A Boost WLED Driver SOT-26 Pin Definition: 1. Switch 2. Ground 3. Feedback 4. Enable 5. OVP 6. VCC General Description The TS1916 is a step-up (Boost) converter designed for driving up to 10 series white LEDs for backlighting application. The TS1916 uses current mode, 1MHz fixed frequency architecture to regulate the LED current, which is set through an external current sense resistor. It’s low feedback voltage reduces power loss and improves efficiency. The OVP pin monitors the output voltage and turns off the converter if an over-voltage condition is present due to an open circuit condition. The TS1916 includes under-voltage lockout, current limiting and thermal shutdown protection preventing damage in the event of an output overload. Features ● 2.5V to 5.
