Introduction

The MD8941 is a high frequency (2MHz) step-down, non-synchronous buck converter with integrated internal high-side high voltage power MOSFET. It provides 0.6A (or less) highly efficient output. The wide 4.2V to 40V input range allows a variety of applications in automotive environment, and 2uA shutdown quiescent current allow applications in battery power systems. Additional protection features are included such as Over Current Protection, Thermal Shutdown and Under Voltage Lockout. The MD8941 is available in the cost-effective SOT23-6L packages.
