Pimoroni Bench Power Module for Yukon (5A Step-down DAC)

Deliver a programmatically adjustable output from 3 V to 12 V for your Yukon projects with a compact 5 A step down regulator based on TPS54A24. Real time RP2040 PWM control turns voltage into a simple knob for precise fan speed or LED brightness.

• 3 V to 12 V output, 5 A continuous, 10 A peak
• 5 V lock via cuttable underside trace for fixed output
• Two exposed digital IO pads with 3.3 V and GND for sensors
• Voltage, temperature and power good monitoring
• 5 mm spaced screw terminals for secure wiring
• Fully assembled; soldering only required for digital IO use
• Compatible with Pimoroni Yukon
• Measurements 24 x 20 x 15.3 mm

Usage examples:

• Control 12 V PC fan speed with PWM for airflow testing
• Dim single colour LED strips with smooth transitions
• Close the loop by reading a sensor on the IO pads and adjusting output in code

Notes:

• For full 12 V output, Yukon input must be at least 12 V; otherwise output is limited to input voltage
• Uses RP2040 PWM hardware; up to four modules can operate at once
• PWM mapping: Slots 1 and 5 use PWM 0B; Slots 2 and 6 use PWM 2B; Slot 3 uses PWM 4B; Slot 4 uses PWM 6B
• MicroPython library and examples available
