ISL70003ASEH
Electrical Specifications Unless otherwise noted, PVINx = AVDD = DVDD = 3V - 13.2V; GND = AGND = DGND = PGNDx = SGND = 0V;
POR_V_IN = 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; I_OUT = 0A; T_A = T_J = +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. (Continued)

NOTES:
10. Typical values shown are not guaranteed.
11. The 0A to 9A output current range may be reduced by Minimum LXx On Time and Minimum LXx Off Time specifications.
12. Limits established by characterization or analysis and are not production tested.
13. Parameters with MIN and/or MAX limits are 100% tested at -55°C, +25°C and +125°C, unless otherwise specified.
