SY7201 30V High Current Boost LED Driver Preliminary Specification General Description Features SY7201 is a DC/DC step-up converter that delivers an • Input voltage range 2.5 to 30V accurate constant current for driving LEDs. Operation • Switch current limit 2A at a fixed switching frequency of 1MHz allows the • Drives LED strings up to 30V device to be used with small value external ceramic • 1MHz fixed frequency minimizes the external capacitors and inductor. LEDs connected in series are components driven with a regulated current set by the external • Internal softstart limits the inrush current resistor. The SY7201 is ideal for driving up to eight • Open LED overvoltage protection white LEDs in series or up to 30V. • RoHS Compliant and Halogen Free • Compact package: SOT23-6 pin Ordering Information SY7201SY7201 (( )) □□□□□□□□□□□□□□□□ □□□□□□□□□□□□□□□□ TemperatureTemperature CodeCode Applications Package CodePackage Code Optional Spec CodeOptional Spec Code • GPS Navigation Systems Temperature Range: -40°C to 85°C • Handheld Devices Ordering Number Package type Note • Portable Media Players SY7201ABC SOT23-6 2A Typical Applications L
