SY7203 - 30V High Current Boost LED Driver

General Description

SY7203 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.

Key Features

  • Input voltage range: 2.8 to 30V.
  • Switch current limit: 4A.
  • Drives LED strings up to 30V.
  • 1MHz fixed frequency minimizes the external components.
  • 20kHz~1MHz wide dimming frequency range for EN/PWM pin.
  • Internal softstart limits the inrush current.
  • Open LED over voltage protection.
  • RoHS Compliant and Halogen Free.
  • Compact package: DFN3X3-10.

Application Note:AN_ SY7203 30V High Current Boost LED Driver Target Design Specification General Description SY7203 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. The LED current is programmable through the external resistor. The device also supports PWM dimming for accurate LED current control. SY7203 is ideal for driving up to eight white LEDs in series or up to 30V.
