Applications include:
- Smart Outlets
- High Voltage Battery Systems
- Remote Sensors
- Utility Meters
HV Series Configuration plus Current Source
The HV MuxCapacitor plus Current Source is an AC-DC lighting controller for low to medium power LEDs. The HV MuxCapacitor stages enable small form factor packaging without using bulky inductors and large capacitors. The regulated current source is set by an external resistor.
Applications include:
- LED Lighting
- Smart Lighting Fixtures
- Smart Outlets
Isolation
The MuxCapacitor with isolation is an AC-DC transformer-less voltage converter for low power IoT applications. A capacitive power driver and receiver replaces the traditional transformer offering 3kV isolation enabling small form factor packaging.
Applications include:
- Remote Sensors
- IoT & IIoT Gateways
- Smart Outlets
- Consumer Appliances User Interface
Standby Power
The MuxCapacitor standby power chipset integrates into a high power SMPS to provide the power under low demand “standby” conditions. The chip set monitors the load conditions and its line side controller enables the main SMPS when the load “wakes-up.” A capacitive power driver provides the safety isolation.
Applications include:
- Gaming PCs, Game Consoles
- Servers
- Large Flat Panel Displays
- Power Inverters
- Consumer Appliances
