Specification AgeRangeDescription : adult Brand : Lufasa BulletPoint : 20 pcs MOSFET 2SK1590 SOT-23-3 2SK1590 BulletPoint1 : The MOSFET Power Switch and Buck Regulator (Low-Side) can be powered with up to 12V and control up to 10A, all while providing a sweet 3.3V. BulletPoint2 : The MOSFET Power Switch and Buck Regulator (Low-Side) is one product we needed at SparkFun, so we figured other folks might have the same problem. Power the board with up to 12V and control up to 10A, all while providing a sweet 3.3V to your control board. BulletPoint3 : Features: Input Voltage Range: 4.5V to 12V, LMR14203 Step Down Voltage Regulator, Configured to Output 3.3V/300mA, PSMN7R0-1000BS N-Channel MOSFET, Configured as a Low-Side Switch, Connectors, Input: 5.5mm x 2.1mm Barrel Jack (Center-Positive) Output: Poke-Home Connectors, Control: 1x4 Female Headers, 0.1"-spaced PTHs, Built-in Flyback Diode on Load. BulletPoint4 : The SparkFun MOSFET Power Switch and Buck Regulator (Low-Side) combines two circuits into one board: an LMR14203 buck regulator configured to output 3.3V and an N-channel MOSFET (PSMN7R0-100BS) configured as a low-side switch. A flyback diode is also on the load side for devices with back EMF! Simply pull the CTL pin low to activate the load. BulletPoint5 : A MEAS PTH jumper is also included for those interested in precisely measuring the current consumption of the system. Note: While the MOSFET is rated to 100A/100V, we don't recommend you go much above 10A as the PCB polygon pours and traces become the limiter.
