TIDA-011001
Quad-channel, 6A, 0V-to-5V programmable power supply reference design
TIDA-011001
概述
This reference design presents a high-density, four-channel, digitally controlled programmable power supply targeting burn-in and reliability test applications. The design support 12VDC input bus and delivers four independently regulated output channels, each adjustable from 0V to 5V with a maximum continuous output current of 6A per channel.
The control architecture centers on C2000™ real-time microcontroller (MCU), which executes a 2P2Z (two-pole, two-zero) digital compensator. A 16-bit quad-channel DAC dynamically modulates the buck power module output by feedback-pin current injection. While a 24-bit, 16-channel SAR ADC simultaneously captures current and voltage telemetry with integrated low drift PGA, the design can achieves a load regulation error of less than ±0.005% of full scale across the full load range.
特性
- Four independent output channels programmable from 0V to 5VDC
- Current clamping integrated in the digital control loop; no external analog limiting circuitry required
- High accuracy load regulation:
- Voltage load regulation: < ±0.25mV (±0.005% of 5V Full Scale)
- Current load regulation: < ±0.3mA (±0.005% of 6A Full Scale)
- 16-bit DAC resolution for sub-millivolt output voltage setpoints
- Simultaneous 24-bit Telemetry with multichannel precision SAR ADC for synchronous current and voltage monitoring at up to 125kSPS per channel.
- Output voltage settling time < 200µs from no-load to full load condition
