ISL70003SEH Datasheet, PDF (10/32 Pages) Intersil Corporation – Acceptance tested to 50krad

ISL70003SEH
Electrical Specifications Unless otherwise noted, V_IN = AVDD = DVDD = PVINx = EN = 3V - 13.2V; GND = AGND = DGND = PGNDx =
GNDx = 0V; POR_V_IN = FB = 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 = 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 - 300rad(Si)/s; or over a total ionizing dose of
50krad(Si) with exposure at a low dose rate of <10mrad(Si)/s. (Continued)
