TPS61050 - Boost Converter

Description

The TPS6105x device is based on a high-frequency synchronous-boost topology with constant current sink to drive single white LEDs.

The device uses an inductive fixed-frequency PWM control scheme using small external components, minimizing input ripple current.

Features

  • 1 Four Operational Modes.
  • Torch and Flash up to ILED = 1200 mA.
  • Voltage-Regulated Boost Converter: 4.5 V, 5 V, and 5.25 V.
  • Shutdown: 0.3 μA (Typical).
  • Total Solution Circuit Area < 25 mm2.
  • Up to 96% Efficiency.
  • I2C-Compatible Interface up to 400 kbps.
  • Integrated LED Turnon Safety Timer.
  • Zero Latency TX-Masking Input (TPS61050).
  • Hardware Voltage Mode Selection Input (TPS61052).
  • Integrated ADC for LE.
