Introduction

The MAX1845ETX is a highly efficient, pin-compatible upgrade to the MAX1845E. It is a step-down DC-DC controller that operates from a 2V to 5.5V or 4.5V to 28V supply and can drive two external N-channel MOSFETs to produce output voltages as low as 0.6V. The controller features internal compensation, current-mode control, and a precision reference, making it easy to use.
