DC/DC POWER SUPPLIES
mobile platform for MID includes 10 DC/DC switching
regulators, nine are included in the 900841 PMIC, and one is
implemented in the companion chip, 900842. Six out of the
nine regulators are Buck converters, and the remaining three
are Boost converters, and these can be set to work in the
following operation modes:
Buck converters Operation Modes Selections (VCC,
VNN, VDDQ, V21, V15, VYMX3G)
• OFF - The regulator is switched off and the output voltage
• PFM - The regulator is switched on and set to PFM mode
• Automatic Pulse Skip - The regulator is switched on and
• PWM - The regulator is switched on and set to PWM

regulator moves automatically between pulse skipping
and full PWM mode depending on load conditions.
