ELECTRICAL CHARACTERISTICS (continued)

(Circuit of Figure 1, VIN = 10V, VCC = VDD = VSHDN = VPGDIN = VPSI = VILIM = 5V, V3P3 = 3.3V, DPRSLPVR = GNDS = GND, VCSP1

= VCSN1 = VCSP2 = VCSN2 = 1.0000V, FB = FBAC, RFBAC = 3.57kΩ from FBAC to CSN1, D6–D0 = [0101000]; MAX17082/MAX17482:

VSLOW = 5V; MAX17021: DPRSTP = GND; TA = -40°C to +105°C, unless otherwise noted.) (Note 4)

tBOOT

Skip mode after output reaches the regulation

voltage or PWM mode, measured at FB with

respect to the voltage target set by the VID code

(see Table 4)

Soft-start, soft-shutdown, skip

mode, and output have not

reached the regulation voltage,

measured at FB

IMVP-6.5

(MAX17082)

IMVP-6+

(MAX17021)

Measured at FB with respect to the voltage target

set by the VID code (see Table 4)

Measured from the time when FB reaches the

boot target voltage (Note 3)

Measured at startup from the time when CLKEN

goes low
