LTC3622EDE#TRPBF

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.

Here are the typical features of the LTC3622EDE#TRPBF (LTC3622 family). For exact specs, consult the datasheet.
