LEDDr 45V 1800mA SO-8 SMD Description

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 protection functions such as current limitation and overtemperature shutdown. The integrated soft-start feature avoids a current and voltage over shot at the output during start-up of the device.
