Resistors A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. It is a conductor that impedes the flow of electric charge through it, creating electrical resistance. Such resistance results from collisions between free electrons and the crystal lattice of the conductor’s atoms. This is the main property of resistors. […]

The LTC7820 is a fixed ratio high voltage high power switched capacitor/charge pump controller. The device includes four N-channel MOSFET gate drivers to drive external power MOSFETs in voltage divider, doubler or inverter configurations. The device achieves a 2:1 stepdown ratio from an input voltage as high as 72V, a 1:2 step-up ratio from an […]
