JA is measured in free air with the component mounted on a high effective thermal conductivity test board with direct attach features. See TB379.

8. For

JC, the “case temp” location is the center of the package underside.

9. For

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

10. EN, FB, PORSEL and REF pins.

11. M/S, SYNC, TDI, TDO and ZAP pins.

12. For operation in a heavy ion environment tested at LET = 86.4MeV•cm2/mg with +125°C (TC).

Electrical Specifications Unless otherwise noted, VIN = AVDD = DVDD = PVINx = EN = M/S = 3V or 5.5V;

GND = AGND = DGND = PGNDx = TDI = TDO = ZAP = 0V; FB = 0.65V; PORSEL = VIN for 4.5V ≤ VIN ≤ 5.5V and GND for VIN < 4.5V,

SYNC = LXx = Open Circuit; PGOOD is pulled up to VIN with a 1kΩ 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 15). Boldface limits apply across the operating temperature range, -55°C to +125°C; over a total

iodizing dose of 100krad(Si) with exposure at a high dose rate of 50 - 300krad(Si)/s; and over a total iodizing dose of 50krad(Si) with exposure at a low

dose rate of <10mrad(Si)/s.
