App note: Features of third generation SiC MOSFET
App note from Toshiba on their new improved SiC MOSFET from previous generation which handles more higher output applications like UPS, Solar inverters and EV charging stations. Link here (PDF) Silicon Carbide(SiC) is attracting attention as a next generation power-semiconductor material that can withstand higher voltages and lower losses than conventional Silicon(Si).Continuing from our second […]
App note: Simple guide to improving ripple rejection ratio of LDO regulators
App note from Toshiba on improving LDO regulators PSRR. Link here (PDF) This document explains the principles of suppressing ripple of the output voltage, which is caused by the ripple of the input , i.e. the ripple compressibility (PSRR). It also explains the frequency characteristics of PSRR and the effects of the output capacitor.
App note: Tips for selecting level shifters/voltage translation ICs
Reference app note from Toshiba about voltage translator selection. Link here (PDF) This application note discusses how to select the right level shifter (also known as voltage translation IC). In some cases, CMOS logic ICs with a TTL-level input or an open-drain output provide levelshifting without using costly level shifters. It is therefore important to […]
App note: Bipolar transistors maximum ratings
Deep dive on to the maximum ratings of bipolar transistors presented in this app note from Toshiba. Link here PDF! For transistors, the maximum allowable current, voltage, power dissipation and other parameters are specified as maximum ratings. The absolute maximum ratings are the highest values that must not be exceeded during operation even instantaneously. When […]
App note: Comparison of SiC MOSFET and Si IGBT
App note from Toshiba on the advantages of Silicon carbide (SiC) MOSFET over silicon (Si) IGBT. Link here PDF! Silicon carbide (SiC) comprises silicon (Si) and carbon (C) atoms. Each atom is surrounded by four different atoms in the form of a regular tetrahedron. SiC is a compound semiconductor with the densest tetrahedral arrangement. SiC […]
App note: Application precautions: Power MOSFET application notes
Toshiba’s application note on the things to consider when picking a power MOSFET. Link here (PDF) This document explains selecting MOSFETs and what we have to consider for designing MOSFET circuit, such as temperature characteristics, effects of wire inductance, parasitic oscillations, avalanche ruggedness, and snubber circuit.
