Overview

The MAX25223 is a small, automotive grade synchronous buck converter with integrated high-side and low-side switches. The device is designed to deliver up to 3.5A with input voltages from +3V to +36V while using only 5μA quiescent current at no load. The MAX25223 provides an accurate output voltage of ±2% within the normal operation input range of +6V to +18V. With 65ns minimum ontime capability, the converter is capable of large input-to-output conversion ratios. Voltage quality can be monitored by observing the PGOOD signal. MAX25223 can operate in drop-out by running at 99% duty cycle, making it ideal for automotive and industrial applications. The IC offers standard parts with fixed output voltages of 3.3V and 5V. Other fixed output voltages in the range of 3V to 5.5V are also available on request. Frequency is internally fixed at 2.1MHz, which allows for small external components, reduces output ripple, and guarantees that there is no AM interference. A 400kHz option is also offered to provide minimum switching losses and maximum efficiency. MAX25223 automatically enters skip mode at light loads with ultra-low quiescent current of 5μA at no load. It offers pin-enabled spread-spectrum frequency modulation designed to minimize EMI-radiated emissions due to the modulation frequency. The MAX25223 comes in a small 4mm x 4mm 20-pin SWTQFN package and uses very few external components. The intelligent package layout results in an extremely low-noise solution with superior EMI performance.
