MAX15569
2-Phase/1-Phase QuickTune-PWM Controller with
Serial I²C Interface
Electrical Characteristics (-40°C to +105°C) (continued)
(Circuit of Figure 1. V_IN = 10V, V_BIAS = 5V, VTT = 1.8V, EN = BIAS, GNDS = AGND, VFBAC = V_FB = VCSP_ = V_{CSN_} = 1V
[SETVOUT register 0x07h set to 0x33h]. T_A = -40°C to +105°C, unless otherwise noted.)

Note 2: The equation for the target voltage V_TARGET is: V_TARGET = the output of slew control DAC, where V_DAC = 0V for
shutdown, V_DAC = V_BOOT during startup; otherwise V_DAC = SETVOUT. The output voltages for all possible codes are
given in Table 3.
Note 3: On-time and minimum off-time specifications are measured from 50% rise to 50% fall at the DRVPWM_ pin. Actual in-circuit
times can be different due to MOSFET driver characteristics.
Note 4: Guaranteed by design. Not production tested.
