General Description

The SY8718A1 is a high efficiency synchronous stepdown LED regulator that achieves up to 2.0A output current.

It operates at 1MHz and integrates two very low RDS(ON) power switches to minimize and reduce the external components.

It supports the PWM dimming duty 5%-100% to achieve dimmable LED lighting application.

Key Features

  • Wide Input Range: 4V-23V.
  • Up to 2.0A Output Current Capability.
  • Low RDS(ON) for Internal Switches High Side/Low Side:125mΩ/75mΩ.
  • Fixed 1MHz Switching Frequency.
  • Cycle by Cycle 3.5A Peak Current Limit for High Side and 2.5A Valley Current Limit for Low Side.
  • High Accuracy for Low Dimming Scale.
  • Output Voltage Discharging.
  • Over Temperature Protection.
  • Compact Package: TSOT23-6.
