STCF07 - High power buck-boost white LED driver

Description

The STCF07 is a dedicated, size-optimized solution for driving a power LED.

The device is a buck-boost converter which guarantees proper LED current control over all possible battery voltage and LED forward voltage conditions.

Features

  • Buck-boost DC-DC converter Drives one power LED up to 1 A in flash mode Drives one power LED up to 800 mA in continuous mode LED temperature protection Output current control 1.8 MHz (typ. ) fixed frequency PWM Synchronous rectification High efficiency across the total input voltage range Operational modes:.
  • Shutdown mode.
  • High current mode: up to 1 A.
  • Low current mode: from 20 mA Adjustable current in both modes Pe.
