Description 40V High Current Boost LED Driver
Datasheet SY7301A-Silergy.pdf

General Description

SY7301A develops a step-up DC/DC converter that delivers an accurate constant current for driving LEDs.

Operating at a fixed switching frequency of 1MHz allows the device to be used with small value external ceramic capacitors and inductor.

LEDs connected in series are driven with a regulated current set by the external resistor.

Key Features

  • Input voltage range: 2.8 to 40V.
  • Switch current limit:2A.
  • Drives LED strings up to 40V.
  • 1MHz fixed frequency minimizes the external components.
  • 200Hz~1MHz dimming frequency for EN/PWM pin.
  • Internal softstart limits the inrush current.
  • Open LED over voltage protection.
  • RoHS Compliant and Halogen F ee.
  • Compact package: TSOT23 -6/DFN3X3-10.
