Frequently Asked Questions
How many PWM outputs does the UCD3138064ARGCR provide, and what switching frequency range do they support?
The UCD3138064ARGCR provides 8 independently programmable PWM output channels. The integrated digital PWM engine supports switching frequencies from below 100 kHz up to approximately 1 MHz per phase, giving designers flexibility to optimize efficiency versus passive component size in multi-phase LLC or phase-shifted full-bridge converter stages.
What ADC resolution does the UCD3138064ARGCR use for feedback sensing, and how does it affect regulation accuracy?
The UCD3138064ARGCR integrates a 12-bit ADC for voltage and current feedback sensing, enabling output voltage regulation accuracy better than 0.5% over the full operating temperature range of -40°C to 125°C. This precision reduces the need for external trim networks and supports tight output rail tolerances demanded by server and FPGA core power applications.
Does the UCD3138064ARGCR support PMBus communication, and what parameters can be read over the bus?
Yes, the UCD3138064ARGCR is PMBus-compliant, supporting a 400 kHz I2C/SMBus interface for real-time telemetry including output voltage, output current, temperature, and input voltage readings. Fault logs, switching frequency, and compensation coefficients can also be read and written remotely, eliminating potentiometer trimming and enabling cloud-managed power supply configurations.
What package does the UCD3138064ARGCR use, and what are the thermal considerations for high-load server PSU designs?
The UCD3138064ARGCR is supplied in a 64-pin QFN (S-PQCC-N64) package with an exposed thermal pad that conducts heat efficiently to the PCB copper plane. In server power supply designs dissipating 1 W to 2 W in the controller, proper 2-oz copper pours and multiple thermal vias beneath the pad keep junction temperatures below the 125°C maximum, ensuring reliable long-term operation.
