TPS659037 Power Management Unit (PMU) for Processor
1 Device Overview
1.1 Features
1
• Seven Step-Down Switched-Mode Power Supply
(SMPS) Regulators:
– One 0.7 to 1.65 V at 6 A (10-mV Steps)
• Dual-Phase Configuration With Digital
Voltage Scaling (DVS) Control
– One 0.7 to 1.65 V at 4 A (10-mV Steps)
• Dual-Phase Configuration With DVS Control
– One 0.7 to 3.3 V at 3 A (10 or 20-mV Steps)
• Single-Phase Configuration
• This Regulator can be Combined With the 6
A Resulting in a 9-A Triple-Phase Regulator
(DVS Controlled)
– Two 0.7 to 3.3 V at 2 A (10 or 20-mV Steps)
• Single-Phase Configuration
• One Regulator With DVS Control That can
also be Configured as a 3-A Regulator
– Two 0.7 to 3.3 V at 1 A (10 or 20-mV Steps)
• Single-Phase Configuration
• One Regulator With DVS Control
– Output Current Measurement in All Except 1-A
SMPS Regulators
– Differential Remote Sensing (Output and
Ground) in Dual-Phase and Triple-Phase
Regulators
