Description
- DESCRIPTION
- The UCD9240 is a multi-rail, multi-phase synchronous buck digital PWM controller designed for non-isolated DC/DC power applications. This device integrates dedicated circuitry for DC/DC loop management with flash memory and a serial interface to support configurability, monitoring and management.
- 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
- • Supported by Fusion Digital Power™ Designer, a Full Featured PC Based Design Tool to Simulate, Configure, and Monitor Power Supply Performance.
