FEATURES
• Fully Configurable Multi-Output and Multi-Phase Non-Isolated DC/DC PWM Controller
• Controls Up To Four Voltage Rails and Up To Eight Phases
• Supports Switching Frequencies Up to 2MHz With 250 ps Duty-Cycle Resolution
• Up To 1mV Closed Loop Resolution
• Hardware-Accelerated, 3-Pole/3-Zero Compensator With Non-Linear Gain for Improved Transient Performance
• Supports Multiple Soft-Start and Soft-Stop Configurations Including Prebias Start-up
• Supports Voltage Tracking, Margining and Sequencing
• Supports Current and Temperature Balancing for Multi-Phase Power Stages
• Supports Phase Adding/Shedding for Multi-Phase Power Stages
• Sync In /Out Pins Align DPWM Clocks Between Multiple UCD9240 Devices
• Fan Monitoring and Control
• 12-Bit Digital Monitoring of Power Supply Parameters Including:
– Input Current and Voltage
– Output Current and Voltage
– Temperature at Each Power Stage
• Multiple Levels of Overcurrent Fault Protection:
– External Current Fault Inputs
– Analog Comparators Monitor Current Sense Voltage
– Current Continually Digitally Monitored
• Over and Undervoltage Fault Protection
• Overtemperature Fault Protection
• Enhanced Nonvolatile Memory With Error Correction Code (ECC)
• Device Operates From a Single Supply With an Internal Regulator Controller That Allows Operation Over a Wide Supply Voltage Range
