Working principle
The LTC3642EDD-3.3#PBF is a non-synchronous boost converter, which means that it utilizes an inductor and a capacitor as a primary part of its circuit. The primary components are coupled to the output via two switch devices, which are controlled by the PWM controller with an array of internal settings. When the switch nodes switch, a current is induced in the inductor, which causes the voltage from the input to be increased to the desired level. The capacitor helps to maintain a steady output, while the switch devices are used to control the current in the inductor. This allows the output voltage to be adjusted to the desired voltage.

The LTC3642EDD-3.3#PBF is an excellent choice for a wide range of applications. With its high efficiency, low quiescent current, and adjustable output voltage, it can provide a reliable power source for many types of electronic components. Additionally, the protection features ensure a safe and reliable operation.
