Single and Dual Output Voltage up to 3 Amps Peak. Section 2. Functional Description 2.1 Output Voltage - AnyVoltageTM Technology The output voltage of the MDx-G15z/MDx-G16/MDx-G30z/MDx-G31 Series is programmed by using the look-up Table 1 to select the resistor value for the VSET and PSET pins. The VSET pin sets the output voltage, and the PSET pin trims the set voltage to a percentage value. For example, to program 2.25V output, a 165K resistor is selected for the VSET pin, and an 11K resistor is selected for the PSET pin. The 165K resistor sets the output voltage to 2.5V and the 11K resistor trims the set voltage off by 10% (or -10%). Using a resistor value greater than 619K or less than 7.68K for the VSET pin disables the switching regulator and sets the SW pin to high impedance. Using a resistor value greater than 619K or less than 7.68K for the PSET pin does not affect the set voltage. If not used, the PSET pin should be tied to ground.

Voltage margining is commonly used during system qualification to evaluate operation at "corner" conditions of voltage, temperature etc. Typically, output voltage will be offset up and down by some percentage (margin) of the nominal value. For the MDx-G15z/MDx-G16/MDx-G30z/MDx-G31 Series the VSET pin/resistor controls the nominal voltage of the switching regulator output while the PSET pin/resistor controls the margin voltage. As can be seen in Table 1, the PSET pin allows the margin to be set as high as 10% above and as low as -10% below the nominal setpoint estab- Doc. No. MV-S101948-00, Rev. C Page 10 Copyright (c) 2004 Marvell Document Classification: Proprietary Information August 26, 2004, Advance Functional Description Output Voltage Margining lished by VSET. Depending on the value of the PSET resistor intermediate points of 7.5%, 5% and 2.5% can also be accessed. For example, if an application calls for a nominal output voltage of 1.5V then Table 1 prescribes a value of R1 for the VSET resistor. This selection is shown in Figure 6 connected to the VSET pin. To offset the voltage above and below the nominal value, the PSET pin can be used with resistor values again from Table 1. Additionally, switches S1 and S2 can be alternately closed to select from the two resistors - R3 and R2 (offset values) for PSET. If more offsets are required more switches and resistors may be used. As shown in the figures below, if S1 is closed and S2 opened a positive 5% offset would be added to the nominal 1.5V output yielding 1.575V. Conversely, if S1 is opened and S2 closed the output would be offset to -5% from 1.5V, or 1.425V. Finally with both S1 and S2 opened the output would return to the nominal 1.5V. Thus voltage margining can be simply and reliably implemented with a minimum of components and design effort.
