Introduction

The MAX718CSE is a dual-output, step-up DC-DC converter with a precision voltage reference. It is designed to provide regulated 3.3V and 5V outputs from an unregulated input voltage range of 0.9V to 5.5V or 7V to 20V. The device features internal overcurrent and thermal shutdown protection, as well as a shutdown mode that reduces quiescent current to less than 1µA.
