Working Principles
LTC3864EMSE#PBF operates on the principle of current mode control, where the inductor current is sensed and compared to a reference voltage. This feedback loop regulates the duty cycle of the power switch to maintain a stable output voltage. The synchronous rectification mechanism reduces power losses by utilizing a secondary MOSFET to replace the diode typically found in non-synchronous designs. The programmable soft-start feature gradually ramps up the output voltage during startup, preventing excessive inrush current. Overvoltage and overcurrent protection mechanisms safeguard the system from potential faults.
