The LT3502AEDC#TRMPBF is a 2.2 MHz, 500mA Buck Switching Voltage Regulator in DFN package made by Analog Devices. It is a highly efficient, monolithic integrated step-down regulator that uses a current-mode architecture to deliver up to 500mA of continuous output current at a switching frequency of 2.2MHz. This device includes a low dropout voltage, programmable switching frequency, internal compensation, current-mode control, and requires only two external components to set the output voltage. The internal N-channel MOSFET provides output current up to 500mA. The LT3502AEDC#TRMPBF also features a logic enable input, Improved line regulation and short-circuit protection. These features allow the LT3502AEDC#TRMPBF to be used in a wide variety of applications like a wide range of portable applications, including cell phones, PDAs, MP3 players, notebook computers, and other battery-powered devices.
