IC Power Supplies (83 suppliers)

IC power supplies are manufactured as integrated circuits.

IC Switching Voltage Regulators (108 suppliers)

IC switching voltage regulators are integrated circuits (ICs) that store energy in an inductor, transformer, or capacitor and then use this storage device to transfer energy from the input to the output in discrete packets over a low-resistance switch.

IC Voltage Regulators (306 suppliers)

IC voltage regulators are three-terminal devices that provide a constant DC output voltage that is independent of the input voltage, output load current, and temperature. IC voltage regulators are used in power supplies that hold their output voltage constant over a wide range of load variations.

LCD Drivers (92 suppliers)

LCD drivers are semiconductor chips used to power and control liquid crystal displays (LCDs).

LED Drivers (228 suppliers)

LED drivers control the amount of current and voltage supplied to light emitting diodes (LEDs), when in operation.

Power Bipolar Transistors (77 suppliers)

Power bipolar transistors are semiconductors in which a base n-type or p-type layer is sandwiched between emitter and collector layers of the opposite type. The junctions between the semiconductor sections amplify weak incoming electrical signals.

Power MOSFET (163 suppliers)

Power MOSFETs are majority carrier devices which have high input impedance and do not exhibit minority carrier storage effects, thermal runaway, or secondary breakdown. Power MOSFETs have higher breakdown voltages than bipolar junction transistors (BJTs) and can be used in higher frequency applications where switching power losses are important.

Power over Ethernet (PoE) Controllers (38 suppliers)

Power over Ethernet (PoE) controllers are used to control the delivery of DC power and data from power source equipment (PSE) to powered devices (PD).

PWM Amplifier Chips (42 suppliers)

Pulse width modulated (PWM) amplifier chips generate a current that switches between high and low output levels. PWM amplifiers have a much higher power capability for a given volume than linear amplifiers. They are also less expensive.

Semiconductor Power Modules (16 suppliers)

Semiconductor Power Modules contain power switches and rectifiers etc, and are offered in various topologies, voltages and current ratings. Common topologies include three-phase inverter stages with input bridge rectification and brakes, boost converters, and multi-level inverters. Power modules using IGBTs are often known as IGBT modules. SiC is also available in modules.

Solid State Power Controllers (SSPC) (36 suppliers)

Solid state power controllers (SSPC) are semiconductor devices that control power (voltage and/or current) supplied to a load. They perform supervisory and diagnostic functions in order to identify overload conditions and prevent short circuits.

Supervisory Circuits and Battery Monitor Chips (98 suppliers)

Supervisory circuits and battery monitor chips are semiconductor devices that detect and monitor voltage levels in power supplies, microprocessors, and other systems.

Varistors (175 suppliers)

Varistors are voltage-clamping devices that can absorb current without damage. They are typically used in surge protection devices.

Voltage Reference Chips (82 suppliers)

Voltage references are electronic circuits that produce a constant output voltage (reference) that is used to compare other voltages in a system.

Voltage-to-Frequency Converter Chips (10 suppliers)

Voltage-to-frequency converter chips provide a signal frequency output as a function of an analog input voltage.
