Description

Datasheet The MAX639 /MAX640/MAX653 step-down switching regulators provide high efficiency over a wide range of load currents, delivering up to 225mA. A current- Oct 10, 2014 If less power is required, use the MAX639 /MAX640/MAX653 step-down converters with on-chip FETs, which allow up to a 225mA load current. MOSFETs at loads greater than 10W. If less power is required, use the MAX639 / MAX640/MAX653 step-down converters with on-chip FETs, which allow up to a. 9V-to-3.3V step-down converters extract maximum battery energy. ( MAX639 /640/ 653). 17. 94%-efficient step-down regulators produce no sub-fundamental. May 26, 2010 two MAX639 high efficiency DC-DC converters. One converter is always on and provides 3.3V to the propeller chip. When the propeller is
