processor’s sequencing requirements. If adherence to this sequencing specification is not
required, connect IN5 to V1, V2, or another supply between 2.35V and V IN . See the Linear
Regulators (REG5–REG8) section for more information .
REG5 Linear-Regulator Output. V5 defaults to 1.8V and is adjustable from 1.7V to 2.0V through

the serial interface. The input to the V5 regulator is IN5. Use V5 to power VCC_MVT, VCC_BG,
VCC_OSC13M, and VCC_PLL on Marvell PXA3xx processors. V5 is internally pulled to AGND
through 2k ? when REG5 is shut down.

REG4 Power Input. Connect a 4.7μF ceramic capacitor from PV4 to PG4. All PV pins and IN must
be connected together externally.
REG4 Switching Node. Connect LX4 to the REG4 inductor. LX4 is high impedance when REG4 is
shut down.
REG4 Power Ground. Connect PG1, PG2, PG3, PG4, and AGND together. Refer to the MAX8660 EV
kit data sheet for more information.
REG2 Voltage Select Input. SET2 is a tri-level logic input. Connect SET2 to select the V2 output

the REG2 soft-start period. Changes to SET2 after the startup period have no effect.
REG6 Linear-Regulator Output. REG6 is activated and programmed through the serial interface to

output from 1.8V to 3.3V in 0.1V steps. REG6 is off by default. V6 is internally pulled to AGND
through 350 ? when REG6 is shut down. V6 optionally powers VCC_CARD1 on Marvell PXA3xx
processors.
