In the last installment of Circuit VR, we walked around a simplified buck converter. The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed ...

At first, you might think it doesn’t have much effect, but zoom in on the output voltage ... buck converters will use two FETs. Some will reduce switching frequency based on load. Then there are ...

Normally, a boost converter would only be used when the output voltage minimum is about 1.5 times the input ... This simplifies sensing of the LED current, unlike the buck converter where we have to ...

The TPSM83102, for example, is a buck-boost converter in a µSiP module that ... EVM operating with a 5-V input and a 1.2-V, 6-A output. Power supplies are critical components of electronic ...

DC-DC converter chips provide a regulated DC voltage output from a different, unregulated input voltage. They are used in power management applications and incorporate several conversion technologies.

The boost converter is optimized for current load up to 20mA and 3.3V to 15V selectable output voltage ... 055UMC_DCDC_01 is high-efficiency step-down DC-DC switching buck converter targeted for ...
