Simple MOSFET Switching Circuit – How to turn on / turn off N-Channel and P-channel MOSFETs A MOSFET is a type of transistor that uses an electric field to control current flow, and is widely used in switching and amplification circuits. MOSFET stands for Metal Oxide Semiconductor Field Effect Transistor, which has a gate. For simplicity, you can imagine this gate like a water tap. You rotate the tap counter-clockwise the water starts flowing out of the tap.… |

Infineon's 1EDN7550 and 1EDN8550 Gate Drivers to Solve Ground-shift Issues in SMPS When a power MOSFET is switched on or off in a switched-mode power supply (SMPS), parasitic inductances cause ground shifts, which can lead to uncontrolled switching of gate driver ICs. Sometimes it may even result in electrical overloading of power MOSFETs and failure of SMPS. Infineon Technologies offers the 1-channel low-side gate driver ICs 1EDN7550 and 1EDN8550 in order… |
