The Future of Analog IC Technology MP2481 36V 1 2A 1 4MHz White LED Driver DESCRIPTION The MP2481 is a 36V 1 2A white LED driver suitable for either step down or inverting step up down applications It achieves 1 2A peak output current over a wide input supply range with excellent load and line regulation Current mode operation provides fast transient response and eases loop stabilization Fault condition protection includes thermal shutdown cycle by cycle peak current limiting input over voltage protection open strings protection and output short circuit protection The MP2481 incorporates both DC and PWM dimming onto a single control pin The separate input reference ground pin allows for direct enable and or dimming control for a positive to negative power conversion The MP2481 requires a minimum number of readily available standard external components and is available in 8 pin MSOP8E package EVALUATION BOARD REFERENCE Board Number Mode EV2481 H 00A Step down EV2481 H 01A Step up down FEATURES 1 2A Maximum Output Current Unique Step up down Operation Buck Boost Mode Wide 4 5V to 36V Operating Input Range for Step Down Applications Buck Mode 0 30 Internal Power MOSFET Switch Fixed 1 4MHz Frequency Analog an

[ Comprehensive information ]

One of the primary functions of an LED driver is to ensure that the LEDs receive a constant current, which is necessary for maintaining consistent brightness and color temperature. To achieve this, many LED drivers use pulse-width modulation (PWM) to control the current flowing to the LEDs, allowing for precise regulation and dimming.
