CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product

reliability and result in failures not covered by warranty.

NOTES:

4. For operation in a heavy ion environment at LET = 86.4MeV•cm2/mg at +125°C (TC) and sourcing 11A load current.

5. For operation in a heavy ion environment at LET = 86.4MeV•cm2/mg at +125°C (TC) with any negative inductor current to sinking -4A load current.

6.

JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech

Brief TB379.

7. For

JC, the “case temp” location is the center of the exposed metal heatsink on the package underside.

8. POR_VIN, FB, NI, VERR, OCSETA, OCSETB, BUFOUT, BUFIN-, BUFIN+, IMON and REF pins.

9. FSEL, EN, SYNC, SEL1, SEL2, and DE pins.

Electrical Specifications Unless otherwise noted, PVINx = AVDD = DVDD = 3V - 13.2V; GND = AGND = DGND = PGNDx = SGND = 0V;

POR_VIN = 0.65V; SYNC = LXx = Open Circuit; PGOOD is pulled up to VREFD with a 3k resistor; REF is bypassed to GND with a 220nF capacitor; SS is

bypassed to GND with a 100nF capacitor; IOUT = 0A; TA = TJ = +25°C. (Note 4). Boldface limits apply across the operating temperature range, -55°C to

+125°C; over a total ionizing dose of 100krad(Si) with exposure at a high dose rate of 50 to 300rad(Si)/s; or over a total ionizing dose of 50krad(Si) with

exposure at a low dose rate of <10mrad(Si)/s.
