MP24833-AGN Monolithic Power Systems

R OVP1 R OVP2 MP24833-A 55V, 3A, White LED Driver The Future of Analog IC Technology DESCRIPTION FEATURES The MP24833-A is a 55V, 3A, white LED driver 3A Maximum Output Current suitable for step-down, inverting step-up/step- Unique Step-Up/Step-Down Operation down, and step-up applications. The MP24833- (Buck-Boost Mode) A achieves 3A of output current with excellent Wide 4.5V-to-55V Operating Input Range load and line regulation over a wide input for Step-Down Applications (Buck Mode) supply range. 0.15 Internal Power MOSFET Switch Current mode operation provides a fast Fixed 210kHz Switching Frequency transient response and eases loop stabilization. Analog and PWM Dimming Full protection features include thermal shutdown, 0.2V Reference Voltage cycle-by-cycle peak current limiting, open-string 6 A Shutdown Mode protection, and output short-circuit protection No Minimum Number of LEDs Required (SCP). Stable with Low ESR Output Ceramic Capacitors The MP24833-A incorporates both DC and Cycle-by-Cycle Over-Current Protection PWM dimming into a single control pin. The (OCP) separate input reference ground pin allows for direct enable and/or dimming control for a Thermal Shutdown Protection positive-to-negative power conversion. Open-String Protection Output Short-Circuit Protection (SCP) The MP24833-A requires a minimal number of Available in a SOIC-8 EP Package readily available, standard, external components and is available in a SOIC-8 EP APPLICATIONS package.
