Mini DC/DC Step-Down (Buck) Converter - 5V @ 1A output
TSR-1 switching buck regulator in SIP-3 package, outputs 5V at 1A from up to 36V input. Up to 94% efficient at +60°C ambient with no heat-sink needed. Requires an additional 10µF+ input capacitor for stability.
Pinout
- +Vin1
Input supply pin for the TSR 1 step-down regulator; Adafruit states 6.5 to 32 VDC input for the 5 V module.
