4 / 7 page 4 www.irf.com ATO28XXT Series T CASE = -55°C to +125°C, VIN = +28V ± 5% unless otherwise specified Specifications Notes to Specifications 1. Tested at each output. 2. Parameter guaranteed by line and load regulation tests. 3. At least 20 percent of the total output power should be taken from the (+5V) main output. 4. Bandwidth guaranteed by design. Tested for 20KHz to 2.0MHz. 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. 6. Above 125 °C case temperature, derate output power linearly to 0 at 135°C case Input voltage -0.5V to +50V DC P ow er O utput Internally lim ited, 17.5W typical S oldering tem perature 300°C for 10 seconds T em perature R ange6 O perating case tem perature -55°C to +135°C Storage case tem perature -65°C to +135°C A bso lu te M axim u m R ating s TEST SYMBOL Condition -55 °C ≤ TC ≤+125°C, VIN = 28 VDC ±5%, CL=0 unless otherwise specified ATO2812T/HB ATO2815T/HB Min Max Min Max Units STATIC CHARACTERISTICS OUTPUT Voltage 1 VOUT IOUT = 0 (main) IOUT = 0 (dual) 1 TC = 25 °C Over Temp TC = 25 °C Over Temp 4.95 4.90 ±11.88 ±11.76 5.05 5.10 ±12.12 ±12.24 4.95 4.90 ±14.85 ±14.70 5.05 5.10 ±15.15 ±15.30 V V V V Current 1,2,3 IOUT VIN = 16, 28, and 40 VDC (main) 0.0 2000 0.0 2000 mA Ripple Voltage 1,4 VRIP VIN = 16, 28, and 40 VDC (dual) 1 VIN = 16, 28, and 40 VDC 0.0 ±208 80 0.0 ±167 80 mA mVp-p BW = DC to 2 MHz (main) VIN = 16, 28, and 40 VDC BW = DC to 2 MHz (dual)) 40 40 mVp-p Power 1,2,3 POUT VIN = 16, 28, and 40 VDC (main) (+dual) (-dual) (total) 10 2.5 2.5 15 10 2.5 2.5 15 W W W W REGULATION Line 1,3 Load 1,3 VRLINE VRLOAD VIN = 16, 28, and 40 VDC IOUT = 0, 1000, 2000mA (main) VIN = 16, 28, and 40 VDC (dual) IOUT = 0, ±84, ±167mA (dual) VIN = 16, 28, and 40 VDC IOUT = 0, 1000, 2000mA (main) VIN = 16, 28, and 40 VDC IOUT = 0, ±84, ±167mA (dual) TC = 25 °C Over Temp 25 ±30 ±60 50 ±60 25 ±35 ±75 50 ±75 mV INPUT Current Ripple Current 4 IIN IRIP IOUT = 0, Inhibit (pin 8) Tied to input return (pin 10) IOUT = 0, inhibit (pin 2) = open IOUT = 2000 mA (main) IOUT = ±167mA (dual) BW = DC to 2MHz 15 40 50 15 40 50 mA mA mAp-p EFFICIENCY EFF IOUT = 2000mA (main) IOUT = ±167mA (dual) TC = ±25°C TC = 25 °C 76 76 % ISOLATION ISO Input to output or any pin to case (except pin 7) at 500 VDC TC = 25 °C 100 100 M Ω Load Fault Power Dissipation 3 PD Overload, TC = +25 °C5 Short Circuit, TC = +25 °C TC = 25 °C 8.0 6.0 8.0 6.0 W Switching Frequency FS IOUT = 2000mA (main) IOUT = ±167mA (dual) 225 275 225 275 KHz Inhibit Open Circuit Voltage VOI 9.0 13 9.0 13 V |
