ANALOG DEVICES LT3663EDCB#TRMPBF DC-DC Switching Buck Regulator, Adjustable, 7.5V to 36V in, 0.8V out, DFN-EP-8

LT3663EDCB#TRMPBF is a current mode step-down switching regulator with programmable output current limit. The current limit accurately controls the system power dissipation and reduces the size of the power path components. The wide operating input voltage range of 7.5V to 36V (60V transient) suits the LT3663 to a variety of input sources, including unregulated 12V wall adapters, 24V industrial supplies, and automotive power. The LT3663 includes a low current shutdown mode, input overvoltage and undervoltage lockout, and thermal shutdown. Internal compensation and boost diode minimize the number of external exponents. Applications include distributed supply regulation, automotive battery regulation, industrial supplies, wall transformer regulation.

• Wide input voltage range from 7.5V to 36V
