2 / 8 page  2 www.irf.com 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. Input voltage -0.5V to +50VDC Power Output Internally limited, 36W typical Soldering temperature 300°C for 10 seconds Recommended Operating temperature -55°C to +85°C Maximum Operating temperature -55°C to +115°C Storage case temperature -65°C to +135°C Absolute Maximum Ratings Temperature Range1 ATR2812D ATR2815D PARAMETER Condition -55 °C ≤ TC ≤ +85°C, VIN = 28 VDC ±5%, CL=0, unless otherwise specified Min Typ Max Min Typ Max Units STATIC CHARACTERISTICS OUTPUT VIN = 16 to 40 VDC Voltage IOUT = 0 to Full Load ±11.76 ±12 ±12.24 ±14.70 ±15 ±15.30 VDC Current 5 0.0 ±1.25 0.0 ±1.0 ADC Ripple Full Load, 20KHz to 2MHz 40 85 40 85 mV p-p Accuracy TCASE = 25 °C, Full Load ±11.88 ±12 ±12.12 ±14.85 ±15.00 ±15.15 VDC Power 1 30 30 W REGULATION Line Load VIN = 16 to 40 VDC IOUT = 0 to Full Load 75 120 75 150 mV mV CROSS REGULATION 6 VIN = 16, 28, and 40 VDC ±5 ±5 % INPUT Voltage Range Current Ripple Current No Load, pin 2 = open Inhibited, pin 2 tied to pin 10 Full Load 16 28 25 40 75 18 50 16 28 25 40 75 18 50 VDC mADC mADC mA p-p EFFICIENCY Full Load TC = +25°C 82 82 % ISOLATION Input to output @500 VDC 100 100 M Ω CAPACITIVE LOAD No effect on performance TC = +25 °C (total for both outputs) 100 100 µF Load Fault Power Dissipation Short Circuit Overload, TC = +25 °C 9.0 14 9.0 14 W W Switching Frequency IOUT = Full Load 500 600 500 600 KHz SYNC Frequency Range7 500 700 500 700 KHz DYNAMIC CHARACTERISTICS Step Load Changes Output Transient Recovery 2 50% Load to 100% Load No Load to 50% Load 50% Load to 100% Load No Load to 50% Load 50% Load to No Load ±100 ±250 25 500 3.0 ±100 ±250 25 500 3.0 mVpk mVpk µs µs ms Step Line Changes Output Transient Recovery 2 Input step 16 to 40 VDC Input step 40 to 16 VDC Input step 16 to 40 VDC Input step 40 to 16 VDC ±180 -600 5.0 5.0 ±180 -600 5.0 5.0 mVpk mVpk ms ms TURN-ON Overshoot Delay 3 VIN = 16 to 40 VDC IOUT = O and Full Load 0.0 14 600 25 0.0 14 600 25 mVpk ms Load Fault Recovery VIN = 16 to 40 VDC 14 25 14 25 ms |
