Adafruit Industries, Unique & fun DIY electronics and kits Mini DC/DC Step-Down (Buck) Converter - 5V @ 1A output [TSR12450] : ID 1065 - Your power supply problems just got SOLVED! These DC/DC converter step-down switching regulators are drop-in replacements for inefficient 78xx linear regulators. The little module may look tiny but inside is a high efficiency converter (up to 94%) which can output 1 Amp at 5V with up to +60°C ambient temperature
Your power supply problems just got SOLVED! These DC/DC converter step-down switching regulators are drop-in replacements for inefficient 78xx linear regulators. The little module may look tiny but inside is a high efficiency converter (up to 94%) which can output 1 Amp at 5V with up to +60°C ambient temperature without the need of any heat-sink or forced cooling.The TSR-1 switching regulators provide other significant features over linear regulators, i.e. better output accuracy (±2 %), lower standby current of 2 mA and no requirement of external capacitors. The high efficiency and low standby power consumption makes these regulators an ideal solution for many battery powered applications.We suggest adding an additional 10uF+ capacitance on the input for additional stability
