The Serial SuperFlash® Kit 2 allows evaluation of Microchip's Serial Flash Devices which are made using the SST SuperFlash® technology. The Serial SuperFlash Kit 2 contains three Serial Flash Daughter Boards. The Serial Flash Daughter Board is an evaluation board designed to interface with the mikroBUS™ connector on the Explorer 16/32 Development Board (DM240001-2). It can also interface with the PICtail™ Plus connector located on the Explorer 16 Development Board (DM240001).

The MCP1642B/D High-Current Synchronous Boost Converter Evaluation Board is used to evaluate and demonstrate Microchip’s MCP1642B/D products. The board can be used to evaluate both package options (MSOP-8 and 2 x 3 mm DFN-8). The MCP1642B/D is capable of regulating the output voltage over 1.8V to 5.5V range and typically can deliver over 400 mA of load current at 3.3V output when supplied from a single 1.5V cell. The Evaluation Board was developed to help engineers reduce the product design cycle time.

The MIC2125/6 Demo Board has been developed to demonstrate the capabilities of the MIC2125/6 device with two adaptive ON-time control architectures:

  • ​Hyper Speed Control (MIC2126)
  • HyperLight Load (MIC2125)


The MIC2125 and MIC2126 Evaluation Boards require only a single power supply with at least 10A current capability. The MIC2125/6 each have an internal VDD LDO, so no external linear regulator is required to power the internal biasing of the IC. In applications with VIN < +5.5V, VDD should be tied to VIN to by-pass the internal linear regulator. The output load can either be a passive or an active load.
The MIC2125/6 Evaluation Boards do not have reverse polarity protection. Applying a negative voltage to the VIN and GND terminals may damage the device. The maximum VIN of the board is rated at 28V.

This MIC2130/1 evaluation board is a high voltage input PWM synchronous buck converter. The MIC2130/1 is a voltage mode controller with a fast hysteretic control loop (FHyCL) employed during fast line and load transients. The MIC2130/1 has an internal transconductance error amplifier, gate drivers, current limit, enable and under voltage lock out and soft start circuitry. The internal gate drivers are designed to drive high current MOSFETs. The evaluation board output voltage is selected by a jumper for pre-selected voltage divider network, 1.8V, 3.3V, 5V or leaving the jumper open for 0.7 V. The maximum current limit is set at 9A. The input voltage is 8V to 40V.
