Targeted Applications; Main Part Numbers - STMicroelectronics STEVAL-IHT008V1 User Manual

Evaluation board objectives
1.3

Targeted applications

Target applications include all applications using a diode-bridge to rectify the line AC
voltage and require the removal of the NTC (or PTC) resistor and the limitation of standby
losses. Such applications include:

telecom power supplies

televisions, DVD and CD players, set-top boxes, etc.

computers

lighting equipment
This demo board is also particularly interesting for applications where AC loads have to be
controlled, such as for valves, fans, pumps, heating resistors, etc. Such applications
include:

wet appliances (washing machines; dish machines; laundry dryers)

cold appliances (fridges, freezers)

air conditioning units
