Working Principle

The LTC3704EMS#PBF operates using an internal switching switch and an integrated clock oscillator. The switching switch is controlled by the clock oscillator to create the alternating power signals that drive the internal switches. The input voltage is applied with a switching pattern, synchronization the frequency. When the rising edge of the clock is reached, the power switch turns on, charging the output capacitor. When the falling edge of the clock is reached, the power switch turns off, allowing the output capacitor to discharge. The result is a regulated output voltage.

The switching controller also uses external resistors and capacitors to provide current and voltage regulation. The resistance of the resistors determines the current level, while the capacitance determines the voltage level at the output. Additionally, the switch has a low-RDS(on) transistor that acts as a linear pass element, allowing for smooth current regulation by adjusting the duty cycle of the switching signal. The power switch is also protected against over-current and over-temperature via the integrated protection circuits.

In conclusion, the LTC3704EMS#PBF is a highly efficient DC/DC switching controller ideal for a variety of applications ranging from consumer electronics, computers and servers, to industrial systems.
