Monolithic Power’s MPM3620A step-down converter here configured to accept 5 - 12 V in and deliver up to 2 A of continuous load current at 5 V out. The board is designed to be mounted directly on top of the Teensy 3.1 above the USB connector, with the 5 V output from the MPM3620A powering the Teensy through VIN. There is a TI TLV70733 LDO voltage regulator which further reduces the voltage to 3V3 at up to 300 mA continuous load current. This small power management board for the Teensy 3.1 allows the powering of the Teensy 3.1, other 3V3 peripherals like sensors that might need more than the Teensy’s on-board regulator can deliver (< 100 mA), and/or power-hungry 5 V peripherals like addressable leds and motors. There is a convenient on/off slide switch which controls the MPM3620A’s enable. There is a red led which is off under normal operation and lights on pre-start, thermal limit, undervoltage and overcurrent thresholds. White circles denote GND. Corrected led circuit.
