The MAX20075D/MAX20076D/MAX25276D are small, synchronous buck converters with integrated high-side and low-side switches. The MAX20076D/MAX25276D are designed to deliver up to 1.2A and the MAX20075D up to 0.6A, with 3.5V to 36V input voltages, while using only3.5µA quiescent current at no load. The devices provide an accurate output voltage of ±2% within the normal operation input range of 6V to 18V. With 20ns minimum on-time capability, the converter is capable of large input-to-output conversion ratios. Voltage quality can be monitored by observing the PGOOD signal. The devices can operate in dropout by running at 99% duty cycle, making them ideal for automotive and industrial applications. The devices offer two fixed output voltages of 5V and 3.3V. In addition, the devices can be configured for 1V to 10V output voltages using an external resistor-divider. Frequency is internally fixed at 2.1MHz, which allows for small external components and reduced output ripple, and guarantees no AM interference. The devices automatically enter skip mode at light loads with ultra-low quiescent current of 3.5µA at no load. The devices offer pin-enabled spread-spectrum-frequency modulation designed to minimize EMI-radiated emissions due to the modulation frequency.The MAX20075D/MAX20076D/MAX25276D are available in small (3mm × 3mm) 12-pin TDFN and side-wettable TDFN packages with an exposed pad, and use very few external components.Design Solution: How to Shrink Your ADAS ECUs: Wrap the Power Management Around the Signal Chain ›Design Solution: Improve Your Automotive ECU Design with a Low-IQBuck Converter ›ApplicationsADASCANClusterNavigationPoint of Load
