AHE28XXS Series
Specifications
Input Voltage
Power Output Internally limited, 17.5W typical for AHE2805S/HB&CH, 22.5W typical for AHE281XS/HB&CH
Soldering 300°C for 10 seconds
Temp Range
Storage -65°C to +135°C
Notes to Specifications
1.
2.
See typical waveforms.
3.
Turn-on delay time measurement is for either an application of power at the input or a signal at the shutdown pin.
4.
For operation at 16VDC, derate output power by 33%.
5.
An overload is that condition with a load in excess of the rated load but less than that necessary to trigger the short circuit
protection and is the condition of maximum power dissipation.
Above +125
°
C case temperature, derate output power linearly to 0 at 135
°
C case.
Recovery time is measured from the initiation of the transient to where V
OUT
has returned to within
±
1% of V
OUT
at 50% load.
