Product Overview
MAX25239AFFA/VY+ is an automotive 2V to 36V, 6A, synchronous buck-boost converter with integrated H-bridge switches. The SYNC input allows three operation modes: skip mode with ultra-low quiescent current, forced fixed-frequency PWM operation, and synchronization to an external clock. The IC also includes spread spectrum frequency modulation to minimize EMI interference. It features a power-OK (POK) indicator, undervoltage lockout, overvoltage protection, cycle-by-cycle current limit, and thermal shutdown. Typical applications are ADAS ECU, infotainment systems, body electronics, start-stop systems, and point-of-load power supplies.
- Meets stringent automotive quality and reliability requirements
- AEC-Q100 qualified high integration and thermally enhanced package reduces BOM cost and board space
- Low quiescent current meets stringent OEM current requirements
- Reduced EMI emissions at switching frequency, spread-spectrum function enabled/disabled by SPS pin
- Protection features improve system reliability
- Shutdown supply current is 5μA typ at VEN = 0V, TA = +25°C
- VCC output voltage is 1.8V at VSUP <gt/> 3.5V, IVCC = 1mA to 50mA
- 8.2A current limit, <lt/>6.5V adjustable voltage
- 2100KHz switching frequency
- 22-pin FC2QFN package, -40°C to +125°C grade 1 automotive temperature range
