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. (Continued)
