Introduction

AI Translation

The MAX20077/MAX25277 is a small, synchronous buck converter with integrated high-side and low-side switches. The device is designed to deliver up to 2.5A (2.0A for the MAX20077ATCC/VY+ variant) with 3.5V to 36V input voltages while using only 3.5μA quiescent current at no load. The device provides an accurate output voltage of ±2% in FPWM mode within the normal 6V to 18V operation input range. 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 device can operate in dropout by running at 99% duty cycle, making it ideal for automotive and industrial applications. The device offers two fixed 5V and 3.3V output voltages. In addition, the device 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. A 400kHz option is also offered to provide minimum switching losses and maximum efficiency. The device automatically enters skip mode at light loads with ultra-low 3.5μA quiescent current at no load. The device offers pin-enabled spread-spectrum-frequency modulation designed to minimize EMI-radiated emissions due to the modulation frequency.
