EUP2588 Datasheet | Eutech Microelectronics

4 Strings High Current White LED Driver with Boost Controller DESCRIPTION Features 3µA shutdown current The EUP2588 is a high power and high efficiency 4 strings in parallel and up to 18 LEDs per boost controller with 4-channel current sinker which is string ideal for large LCD backlighting applications. External PWM Dimming Control EUP2588 uses current mode, fixed frequency Output voltage up to 65V architecture which can clamp the inductor peak current Up to 180m A Drive Capability for Each String each cycle. The switching frequency is programmable Wide Input voltage range 4.5V to 28V by an external frequency setting resistor. It drives an Better than 1.5% LED Current Regulation external MOSFET to boost up the output voltage from Accuracy Between Strings a 4.5V to 28V input supply. The EUP2588 regulates Boost Switching frequency can be programmed the current in each LED string to the programmed by external resistor value set by an external current setting resistor. The Multiple Fault Protections EUP2588 current matching can achieve ± 1.5% and -Current Limit protection regulation accuracy can reach ±2%. -Output Short circuit detection A 3µA shutdown current and 0.85V (ILED@180m A) -Over-temperature protection feedback voltage and Maximum 65V output allows for -Output Over-voltage protection up to 18 high-power LEDs in series will greatly LED current turn off in shutdown mode improve efficiency and reduce power dissipation. Integrated UVLO/ Over Thermal protection Minimal 0.5µs LED On-Time regulation The device supports pulse width modulation (PWM) Thermal Enhanced TSSOP-16 and 16pin brightness dimming. During digital PWM dimming, SOP-16 Packages the WLED current is turned on/off at the duty cycle Ro HS pliant and 100% Lead (Pb)-Free and frequency determined by the PWM signal on the Halogen-Free PWMI pin. b y The EUP2588 integrated multiple protect R functions, ‘ w such as LED Open, LED Short, Output Over Voltage, APPLICATIONS m Over thermal, Input Over...
