Vue d'ensemble

Description

The LTC1772ES6 is a high-efficiency step-down (buck) DC/DC converter controller manufactured by Linear Technology, now part of Analog Devices. It is designed for low-voltage, high-efficiency power conversion applications. The component is capable of driving an external N-channel MOSFET to deliver output currents up to several amperes. The LTC1772ES6 operates with an input voltage range of 2.5V to 9.8V, making it suitable for single lithium-ion cell, 3.3V, or 5V input applications.
Key features include a constant off-time architecture, allowing for constant frequency operation and low output voltage ripple, and a shutdown mode that reduces supply current to 10μA. The device provides efficiencies of over 95% and includes a 0.8V feedback reference, allowing for low output voltage regulation. The LTC1772ES6 is housed in a compact SOT-23 package, making it well-suited for space-constrained applications such as portable electronics, battery-powered devices, and point-of-load power supplies. Its simplicity, efficiency, and compact size make it a popular choice for designers looking for effective power management solutions in low-voltage environments.
