Electrical Specifications

Unless otherwise noted, PVIN = 3V and 18V; PGND = SGND = 0V; LX = Open Circuit; PGOOD is pulled up to PVIN with a 10k

resistor; IOUT = 0A; TJ = TA, rDS(ON) is pulse tested. Boldface limits apply across the operating temperature range, -55°C to

+125°C by production testing; over a total ionizing dose of 75krad(Si) at +25°C with exposure at a low dose rate of

<10mrad(Si)/s.
