Sample Check & Availability |
An example application is shown below. 12 V or 24 V power supplies provide direct power to low-voltage appliances below 5 V.
Ultra-low current consumption solution in standby mode
Power can be supplied directly to the controller IC from a high-voltage source with low current dissipation.
