概述
Description
LTC3622EDE#TRPBF is a Linear Technology (now Analog Devices) dual synchronous buck regulator in a single package. It provides two independent DC-DC buck converters with integrated high- and low-side FETs for high efficiency, adjustable output voltages via external feedback resistors, and common features such as soft-start, enable pins, and current-mode control. Protection includes overcurrent, thermal shutdown, undervoltage lockout, and short-circuit protection. EDE denotes a specific package variant, while TRPBF indicates Tape-and-Rev Pb-free packaging. Typical use is to generate two regulated rails (e.g., core and I/O voltages) for complex digital systems. For exact specs (input range, output voltage ranges, switching frequency, pinout), consult the LTC3622 datasheet and the associated package documentation.
