InTune Automatically Compensated Digital PoL

Controller with Driver and PMBus Telemetry

Electrical Characteristics (continued)

(All settings = factory default, VPWR = VINSNS = 12V, VSGND = VDGND = VPGND = 0V, VOUT = 1.2V, fSW = 600kHz. Specifications are

for TA = TJ = -40°C to +85°C, typical values are at TA = TJ = +25°C. See the Typical Operating Circuit, unless otherwise noted.)(Note 2)
