Product Overview
MAX42402AFLB+ is a 36V, fully integrated synchronous buck converter. This IC is a tiny synchronous buck converter with integrated high-side and low-side switches. The IC can operate in dropout by running at 99% duty cycle, making it ideal for industrial applications. When SYNC is low, this automatically enter skip mode at light loads with an ultralow quiescent current of 27uA at no load. The device has a spread-spectrum frequency modulation option designed to minimize EMI-radiated emissions due to the modulation frequency. Key applications are industrial automation, point-of-load, distributed DC power systems.
- Operating input voltage range from 4.5V to 36V
- 27μA quiescent current in skip mode, 1.5MHz/400KHz switching frequency
- 99% duty cycle operation with low dropout
- High precision for safety-critical applications, accurate Windowed PGOOD
- Precision enable thresholds for fully programmable UVLO thresholds
- Overtemperature, overvoltage, and short-circuit protection
- Adjustable 0.8V to 12V VOUT
- 2.5A maximum load current
- 1.5MHz switching frequency, ±6% spread spectrum
- Operating temperature range from -40°C to +125°C, FC2QFN package
