Monolithic Power Systems, Inc. LED Drivers MP3398AGF

The MP3398AGF is a step-up LED driver designed to control four strings of white LEDs with a maximum current of 350mA per string. It operates within a 5V to 28V input voltage range and features a programmable switching frequency, allowing for flexibility in design. The device ensures current matching accuracy of 2.5% between strings, which is beneficial for uniform brightness across the LED array. This driver supports both analog and PWM dimming modes, making it suitable for various lighting applications. It includes multiple protection features such as over-voltage protection, thermal shutdown, and short-circuit protection, enhancing reliability in operation. The MP3398AGF is available in a TSSOP16-EP package, which is advantageous for space-constrained designs. It is particularly applicable for large LCD panel backlighting, including desktop displays and televisions.
