Infineon® Power LED Driver TLD5085EJ 1.8A DC/DC Step-Down Converter www.DataSheet.net/ Datasheet Rev. 1.1, 2009-12-16 Automotive Power Datasheet pdf - http://www.DataSheet4U.co.kr/ 1.8A DC/DC Step-Down Converter TLD5085EJ 1 Overview Wide Input Voltage Range from 4.75V to 45V Constant Current or Constant Voltage Regulation Drives LEDs in Buck Topology Very low shutdown current consumption (typ. 0.1µA) 370 kHz switching frequency PWM Dimming Integrated power-switch (output current up to 1.8A) Internal Soft-Start function ± 2% output current tolerance (± 4% for full load current range) Small thermally enhanced exposed heatslug package Over Temperature Shutdown AEC Qualified Green Product (RoHS Compliant) PG-DSO-8 (e-Pad) Description www.DataSheet.net/ The TLD5085EJ is a smart LED buck converter with an integrated power-switch, capable of driving up to 1.8A load current with excellent line and load regulation. The main function of this device is to step-down the input voltage and regulating a constant LED current. The constant current regulation is especially beneficial for LED color accuracy and longer lifetime. The TLD5085EJ also has a PWM input which can be used for LED dimming. The switching frequency of 370kHz allows to use small and inexpensive passive components. An Enable function is implemented to reduce the shut-down current consumption to typ. 0.1µA. This IC is suited for use in the harsh automotive environments and provides protect...
