MAX25223ATPA/VY+

MAX25223ATPA/VY+ is a small, automotive grade synchronous buck converter with integrated high-side and low-side switch. 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. It 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. It 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. Frequency is internally fixed at 2.1MHz, which allows for small external components, reduces output ripple, and guarantees that there is no AM interference. Applications include automotive, industrial, high voltage DC-DC converters.
