Maxim Integrated MAX20079 Automotive 36V 3.5A Buck Converter
Maxim Integrated MAX20079 Automotive 36V 3.5A Buck Converter is housed in a small package with integrated high-side and low-side switches. The device can deliver up to 3.5A with input voltages from +3V to +36V while using only 3.5µA quiescent current at no load. The MAX20079 provides an accurate output voltage of ±2% within the normal operation input range of +6V to +18V. The converter is capable of large input-to-output conversion ratios with 65ns minimum ontime capability. Voltage quality can be monitored by observing the PGOOD signal. MAX20079 operates in drop-out by running at 99% duty cycle, making it ideal for automotive and industrial applications.
