LM3565
www.ti.com SNVS957 – JANUARY 2013 4MHz, High-Current Flash LED Driver
Check for Samples: LM3565 FEATURES DESCRIPTION The LM3565 is a 4 MHz fixed-frequency, current
mode synchronous boost converter designed to drive
two series flash LEDs at 930 mA. A high-voltage
current source allows the LEDs to be terminated to
the GND plane eliminating the need for an additional
return trace back to the IC. 1 High Efficiency Synchronous Boost Converter
