The LTC1872ES6#TRPBF is an integrated circuit (IC) manufactured by Analog Devices. It is a Step-Up/Step-Down DC-DC controller that features Boost, SEPIC (Single-Ended, Primary-Inductance, Converter) regulator positive output, and Switch Mode step-up converter. It is available in TSOT-23-6 package configuration.The LTC1872ES6#TRPBF has an operating temperature range of -40°C to 85°C, a peak current of 3A, an exposed pad package, and lower voltage skip mode (LVS). It is particularly designed for fixed and adjustable output voltage applications and offers features including trickle-charge capability, temperature compensation, and a soft-start circuit. It also has wide input voltage range from 2.25 to 40V and high efficiency due to switching frequency of up to 1MHz. The LTC1872ES6#TRPBF is suitable for solar electricity, LED lighting, cyber security and military applications.
