Unauthorized Photocopy and Duplication Prohibited. © 2014 MPS. All Rights Reserved. The Future of Analog IC Technology DESCRIPTION The EV24895-J-00A is an evaluation board for the MP24895GJ, a step-down converter designed in hysteretic current control mode for driving the high brightness LEDs from wide input voltage of 9V to 30V. The MP24895 employs hysteretic control architecture to regulate LED current. Moreover, this control scheme provides optimal circuit stabilization and a very quick response time without loop compensation. The highly accurate LED current is measured through an external high-side current-sense resistor. Its low 100mV average feedback voltage reduces power loss and improves the efficiency. The MP24895 implements PWM and analog dimming together on the EN/DIM pin. The MP24895 includes under-voltage lockout, and thermal overload protection to prevent damage in the event of an output overload. ELECTRICAL SPECIFICATIONS Parameter Symbol Value Units Input Voltage VIN 9 to 30 V Output Voltage VOUT <VIN-3 V LED Current ILED 750 mA FEATURES • Internal 36V MOSFET • Wide 9V to 30V Input Range • 750mA Output LED Current • High Efficiency • Hysteretic Control • PWM and Analog Dimming • 1000:1 PWM Dimming Resolution • UVLO • Thermal Shutdown APPLICATIONS • Low-Voltage Halogen Replacement • Low-Voltage General Illumination • Automotive/Decorative LED Lighting • Signs/Emergency Lighting • LED Backlighting All MPS parts are lead-free and adhere to the RoHS directive.
