TOSHIBA ANNOUNCES NEW PHOTOVOLTAIC-OUTPUT PHOTOCOUPLER

Toshiba Electronics Europe GmbH (“Toshiba”) has launched a new photovoltaic-output photocoupler (“photovoltaic coupler”) housed in a thin SO6L package measuring just 3.84mm × 10mm × 2.1mm, suitable for driving the gates of high-voltage power MOSFETs used to develop a galvanically-isolated solid-state relay (SSR) function. SSRs are semiconductor relay devices that incorporate a photo-TRIAC, a photo-transistor …

INA190-Q1 – 40V, BI-DIRECTIONAL, ULTRA-PRECISE CURRENT SENSE AMPLIFIER

The INA190-Q1 is an automotive, low-power, voltage-output, current-shunt monitor (also called a current-sense amplifier). This device is commonly used for monitoring systems directly connected to an automotive 12-V battery. The INA190-Q1 can sense drops across shunts at common-mode voltages from –0.2 V to +40 V, independent of the supply voltage. In addition, the input pins have an …

SWITCHMODE POWER SUPPLY TOPOLOGIES EXPLAINED

The role of power supply is crucial for electronic circuits because without sufficient power, the circuit cannot function at its optimal level. On the other hand, an exceeded power supply can deteriorate the circuit components by heating effect. There are usually two choices for power supply topologies; Linear Power Supply and Switched Mode Power Supply (SMPS). The linear …

NCH6300HV HIGH VOLTAGE DC-DC POWER BOOSTER FOR NIXIE DISPLAYS

When the switch is open initially, there is not much resistance, so high current flows through the inductor. The energy in the inductor is due to the magnetic fields. When the switch is closed, the impedance in the circuit increases and the current will be reduced. The magnetic field previously created will be reduced in …
