LTC1772ES6#TRMPBF: High Efficiency, Synchronous Step-Down Switching Regulator

The LTC1772ES6#TRMPBF is a state-of-the-art synchronous step-down switching regulator designed by Linear Technology, now part of Analog Devices, that offers high efficiency and performance for power supply solutions. This compact, integrated circuit is engineered to convert a higher input voltage to a lower output voltage with exceptional power efficiency, making it an ideal choice for battery-powered devices, portable electronics, and other space-constrained applications.

Key Features:

• Constant Frequency Operation: The LTC1772 operates at a fixed frequency of 550kHz, which allows for a predictable noise spectrum and the use of small, low-cost capacitors and inductors.
• High Efficiency: Thanks to its synchronous operation, which eliminates the need for an external diode, this regulator achieves efficiencies as high as 96%, thereby reducing heat generation and extending battery life.
• Low Dropout Operation: The strong on-board MOSFETs enable the LTC1772 to maintain regulation even with a very low difference between input and output voltages, making it suitable for applications with tight power budgets.
• Burst Mode® Operation: To maximize battery life, the LTC1772 features Burst Mode operation, which reduces quiescent current to just 10µA during light loads or standby.
• Wide Input Voltage Range: This regulator can operate with input voltages from 2.65V to 8.4V, accommodating a variety of power sources including single-cell Li-Ion batteries.
• Adjustable Output Voltage: The output voltage can be set from 0.8V to the input voltage level, providing versatility for different design requirements.
• Compact Package: Housed in a small TSOT-23 package, the LTC1772ES6#TRMPBF is optimized for space-constrained applications.
