MP1488 800mA Fixed Frequency White LED Driver DESCRIPTION FEATURES The MP1488 is a step-up converter designed for 2.5V to 6V Input Voltage Range driving up to 27 WLEDs (9 strings of 3 WLEDs On Board Power MOSFET each) from a 5V system rail. The MP1488 uses a Drives up to 27 White LEDs at 5V Input current mode, fixed frequency architecture to Up to 92% Efficiency regulate the LED current, which is measured Over 1MHz Fixed Switching Frequency through an external current sense resistor. Its low Open Load Shutdown 104mV feedback voltage reduces power loss and Low 104mV Feedback Voltage improves efficiency. The OV pin monitors the Soft-Start/PWM Dimming output voltage and turns off the converter if an UVLO, Thermal Shutdown over-voltage condition is present due to an open Internal 800mA Current Limit circuit condition. Available in a TSOT23-6 Package The MP1488 includes under-voltage lockout, APPLICATIONS current limiting and thermal overload protection preventing damage in the event of an output Cell Phones overload. Handheld Computers and PDAs Digital Still Cameras The MP1488 is available in a small 6-pin TSOT23 Small LCD Displays package. All MPS parts are lead-free, halogen free, and adhere to the RoHS directive. For MPS green status, please visit MPS website under Quality Assurance.
