ADALM2000 Power Booster Board
The AD-M2KPWR-EBZ is an ADALM2000 add-on board which increases the output current capability up to 700mA. This board can be also used as a standalone benchtop power supply with positive and negative outputs.

Features
- ADALM2000 compatible
- USB Type-C powered (no Power Delivery included)
- Provides two outputs with increased current sourcing capabilities
Description
The AD-M2KPWR-EBZ is a USB Type C powered board capable to increase the output current of ADALM2000’s power supplies.
Inputs:
- USB type C : 4 – 18 V (validated with RPI USB-C power supply - not provided in the kit), 15W (power supply permitting)
- External (screw terminal connector): 4–18V; 20W (power supply permitting)
Outputs: (2 control modes)
- Two variable power supplies that track M2K user supplies:
- 0V to 5V (400mA in USB power mode)
- -5V to 0V (400mA in USB power mode)
- Two variable power supplies, controlled from a potentiometer
- 1.5V to 15V (up to 700mA if powered with 18V)
- -15V to -1.5V (up to 700mA if powered with 18V)
Applications
- General-purpose electronic systems
- Educational applications
- Automated test equipment

Getting started
AD-M2KPWR-EBZ must be supplied either from a 5.1V 3A USB Type C power adapter or from a lab supply using the screw terminal connector. Make sure that the jumper on the P2 connector is on the position corresponding to the chosen supply:
Vext - for external lab supply
Vusb - for USB Type C power adapter
The board has two modes: M2K and POT
In M2K mode the board is plugged into ADALM2000. After that, the programable user supplies of ADALM2000 can be used as usual, but they will source more current. The jumper on the connector P7 must be in M2K- position and the jumper on the connector P6 must be in M2K+ position.

In POT mode the board can be used as a standalone benchtop power supply. The output voltage is adjusted with potentiometers R19 and R20. The output voltage will be available at the same pins: V+ and V-.
