(Circuit of Figure 1. VIN = 10V, VBIAS = 5V, VTT=1.8V,EN=BIAS,GNDS=AGND,VFBAC = VFB = VCSP_ = VCSN_ = 1V

[SETVOUTregister0x07hsetto0x33h].TA = -40°C to +105°C, unless otherwise noted.)

Note 2: The equation for the target voltage VTARGET is: VTARGET=theoutputofslewcontrolDAC,whereVDAC = 0V for

shutdown, VDAC = VBOOT during startup; otherwise VDAC = SETVOUT. The output voltages for all possible codes are

given in Table 3.

Note 3: On-timeandminimumoff-timespecificationsaremeasuredfrom50%riseto50%fallattheDRVPWM_pin.Actualin-circuit

times can be different due to MOSFET driver characteristics.

Note 4: Guaranteedbydesign.Notproductiontested.
