The output connection arrangement has a second semiconducting switch (8) on the output side of the first semiconducting switch and a second control circuit that measures the voltage across the capacitor and the voltage at the output and switches off the second switch if the difference between the...
1. The DC voltage across the capacitor: higher DC voltage reduces capacitance. 2. The AC voltage across the capacitor: lower AC voltage reduces capacitance. You should always check your vendor's capacitor datasheet for actual DC bias characteristic and AC voltage characteristic. In the actual...
Where Vdrop is the voltage drop across the capacitor, I is the current demand, C is the capacitor value and dt is the duration of the current draw. The converter will recharge the capacitor to its original value and in doing so, the converter can exceed its current rating. The voltage d...
DSP core voltage (VOUT1) = 1.2 V DSP core voltage (VOUT2) = 1.0 V Input voltage = 3.3 V Output current = 300 mAHigh-value resistors are used to minimize power losses through the resistive divider. The feedforward capacitor reduces the effect of the gate-to-drain capacitance during ...
DC-DC regulators are indispensable components in modern electronic systems, offering crucial voltage regulation stable and efficient device operation. By converting a wide range of Vin to a precise Vout, these regulators enhance circuits’ performance, reliability, and energy efficiency across various appl...
The boost converter is a class of Switched-Mode Power Supply (SMPS) that contains at least two semiconductor switches (diode/transistor) and one energy storage element (inductor/capacitor). Filters are used to reduce voltage ripple. Usually, the filters are made of capacitors or a combination of...
The RPA100H and RPA200H feature a broad 10:1 input to cover all common voltage ratings in one module. Case Size DC/DC railway converters are often referred to as bricks, half-bricks, and quarter-bricks. A full-brick measures 4.6 x 2.4 x 0.5 inches, a half-brick measures 2.3 x ...

producing a large negative voltage spike as the inductor impedes the change in current passing through it. This action results in a high-frequency noise pulse and, potentially, arcing across the open switch contacts. The voltage spike applied to the DC-DC module’s output (and anything else co...
