MAX15301

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)

Note 2: Limits are 100% production tested at TA = +25°C. Maximum and minimum limits over temperature are guaranteed through

correlation using statistical quality control (SQC) methods. Typical values are expressed as factory-default values also for

configurable specifications within a range.

Note 3: Can go to 100% during a transient.

Note 4: Design guaranteed by bench characterization. Limits are not production tested.

Note 5: The settable output voltage range is 0.6V to 5.0V. This range expands to 0.5V to 5.25V when the voltage margining

function is enabled.

Note 6: Once the MAX15301 locks onto an external synchronizing clock, the tolerance on the capture range is ±10%.

Note 7: See the Voltage Tracking section.

Note 8: Excluding tracking mode.

Note 9: Voltage regulation accuracy is power-stage dependent; adherence to all data sheet design recommendations is required to

achieve specified accuracy.
