30V High Current Boost LED Driver
Preliminary Specification
General Description
SY7201 is a DC/DC step-up converter that delivers an
accurate constant current for driving LEDs. Operation
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. The SY7201 is ideal for driving up to eight
white LEDs in series or up to 30V.
Applications
• GPS Navigation Systems
• Handheld Devices
• Portable Media Players
Features
• Input voltage range 2.5V to 9V
• Switch current limit 2A
• Drives LED strings up to 30V
• 1MHz fixed frequency minimizes the external
components
• Internal softstart limits the inrush current
• Open LED overvoltage protection
• RoHS Compliant and Halogen Free
• Compact package: SOT23-6 pin
