SC4509 Highly Integrated Step-Up Converter for White LED Applications in MLPD-W8-2x2 POPOWER MANAWER MANAGEMENTGEMENT Description Features The SC4509 is a highly integrated step-up DC/DC convert- VIN range: 2.7V 10V er targeted for white LED backlighting applications. It is Integrated Schottky diode designed to drive up to ve LEDs with a wide input voltage 81% ef ciency range of 2.7 to 10 volts. Designed for 20V output voltage, Requires only 4 external components the SC4509 operates with a constant 1.2MHz PWM fre- Up to 20V of output voltage quency. To optimize ef ciency, the feedback voltage is set 30mA maximum LED current to only 199mV, minimizing the power loss in the current Open LED protection (OVP) setting resistor. The product requires only four external 1.2MHz PWM switching frequency components (CIN, COUT, L and R ), making it ideal for Low feedback voltage (20OmV typical) SET applications that require low cost and minimal PCB area. Wide range of PWM dimming Drives up to 5 LEDs The SC4509 offers current limit and over-voltage protec- 500mA switch current limit tion (OVP) to safeguard the device under extreme operat- 220nF output capacitor ing conditions. If the LEDs become disconnected or fail in Available in 2mm x 2mm x 0.75mm MLPD-W8 and an open state condition, OVP circuitry will be activated to SOT23-6 packages shut down the device. The EN/SS pin allows the device Packages are fully WEEE and RoHS compliant to be placed in power-down mode, disabling the control circuitry to reduce input current.
