L6926D1

Voltage Regulators - DC DC Switching Regulators Overview

The L6926D1 is a monolithic DC-DC synchronous step-down regulator designed for high efficiency in single Li-Ion cell applications. It operates with an input voltage range of 2 V to 5.5 V and provides an adjustable output voltage down to 0.6 V via an external divider. The device utilizes a 600 kHz fixed-frequency current-mode architecture, supporting up to 800 mA output current with ±1% accuracy. Key electrical characteristics include low-dropout operation at 100% duty cycle, externally synchronized switching from 500 kHz to 1.4 MHz, and a maximum shutdown supply current of 1 µA.
