说明

The MAX25611A/MAX25611B/MAX25611C/MAX25611D are single-channel HBLED drivers for automotive front light applications such as high beam, low beam, daytime running light (DRL), turn indicator, fog light, and other LED lights. It can take an input voltage from 5V to 36V and can drive a string of LEDs with a maximum output voltage of 65V.

The MAX25611A/B/C/D sense output current at the high side of the LED string. High-side current sensing is required to protect for shorts from the output to the ground or battery input. It is also the most flexible scheme for driving LEDs, allowing boost, high-side buck, SEPIC mode, or buck-boost mode configurations. The PWM input provides LED dimming ratios of up to 5000:1, and the REFI input provides additional analog dimming capability in the MAX25611A/B/C/D. The MAX25611A/B/C/D have built-in spread-spectrum modulation for improved electromagnetic compatibility performance. The MAX25611A/B/C/D can also be used in zeta and Cuk converter configurations if it is necessary in some applications.

The MAX25611A/B/C/D are available in a space-saving 12-pin SWTQFN-EP package. They are specified to operate over the -40°C to +125°C automotive temperature range. The switching frequency is internally set at 350kHzfor the MAX25611A/MAX25611C and 2.2MHz for theMAX25611B/MAX25611D.
