RS+ to GND, as shown in Figure 8 VOUT should not exceed 5V. Select RFB2 (RS+ to GND resistor) ≤ 50kΩ. Calculate

RFB (OUT to RS+ resistor) with the following equation:

RFB1 = RFB2[(

VOUT

VRS+

) − 1]

where VRS+ = programmed VID voltage. Capacitor CFB1 can help improve the phase margin when using a resistive

divider. Determine CFB1 from the following equation:

CFB1 = 1

/ (2 × π × RFB1 × 80k)

When setting the output voltage externally, scale the inductance according to the VOUT/VRS+ ratio. MAX20010EATPA/

V+ parts are programmed with double internal slope compensation to allow for smaller inductance values. Set the

inductance using the following equation:

L = VOUT

/ VRS+ × 220nH / 2
