reliability and result in failures not covered by warranty.
NOTES:
4. θ_JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
5. θ_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
6. For θ_JC, the “case temp” location is the center of the package underside.
7. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
8. For operation in a heavy ion environment at LET = 86.4 MeV•cm²/mg with +125°C (T_C).
9. EN, FB, PORSEL and REF pins.

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 V_IN < 4.5V,
SYNC = LXx = Open Circuit; PGOOD is pulled up to V_IN with a 1k resistor; REF is bypassed to GND with a 220nF capacitor; SS is bypassed to GND with a
100nF capacitor; I_OUT = 0A; T_A = T_J = +25°C. (Note 11). Boldface limits apply over 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.
