ATR28XXD Series
Specifications
T
CASE = -55°C to +85°C, VIN = +28V ± 5% unless otherwise specified
Notes to Specifications
1. Above +85
°C case temperature, derate output power linearly to 0 at +115°C case.
2. Recovery time is measured from the initiation of the input transient to where V
OUT has returned to within ±1% of V
OUT at 50% load.
3. Turn-on delay time measurement is for either an application of power at the input or a signal at the inhibit pin.
4. Load current split equally between +V
OUT and –VOUT.
5. Up to 90% of Full Power is available from either output provided. The total power output does not exceed 30W.
6. 3W load on output under test, 3W to 27W on other output.
7. Sync. Input signal: V
IL = -0.5V Min, 0.8V Max and VIN = 2.5V Min, 11.5V Max for 10% to 90% duty cycle.
