Low-Dropout Voltage Regulator
A Low-Dropout Regulator (LDO) is a type of voltage regulator that provides a stable output voltage even when the input voltage is only slightly higher than the desired output voltage. The term “low-dropout” refers to the minimal difference, or “dropout voltage,” between the input and output voltages required for the regulator to function properly. Key…

IDC 30-Pin Connector Breakout Board
IDC stands for Insulation-Displacement Connector. An IDC Connector Breakout Board is a small circuit board that allows easy access to the individual pins of an IDC (Insulation-Displacement Connector). The IDC connector on the board is typically attached to a ribbon cable, and the breakout board “breaks out” each wire from the ribbon cable to separate,…

DC-DC Boost Converter
A DC-DC boost converter is a type of power converter that steps up (boosts) a DC voltage to a higher level. It is useful in applications where a higher voltage level is required than what is available from the input source. The boost converter typically consists of an inductor, a switch (usually a transistor), a…

DC-DC Buck Converter
A DC-DC buck regulator is a type of voltage regulator that steps down a higher voltage to a lower voltage. The buck regulator operates by controlling the duty cycle of a switching transistor to regulate the output voltage. It is called a “buck” regulator because the output voltage is lower than the input voltage, and…
