LM25116 Synchronous DC to DC Buck Converter 6-36V to 1.25-20V 6A Voltage Regulator 3V 5V 9V 12V 15V 19V Car Power Supply Module

LM25116 High Efficiency Synchronous Buck Converter Module – 6-36V Input, 1.25-20V Adjustable Output, 6A ContinuousProduct Description:This synchronous step‑down (buck) module is based on the LM25116 controller. It accepts an input voltage from 6V to 36V and provides an adjustable output from 1.25V to 20V (buck only – output must be at least 3V lower than input). Delivers 6A continuous(8A peak for <10s) with low output ripple (~10mV @1A). High efficiency (up to 98.5%). Compact size: 49×24×10mm. Ideal for car power supplies, battery regulation, industrial equipment, and DIY variable power supplies.Key Specifications:Input Voltage: 6 – 36V DCOutput Voltage: 1.25 – 20V DC (adjustable, buck only, drop ≥3V recommended)Output Current: 6A continuous, 8A peak (<10 seconds)Output Ripple: ~10mV @ 1ATypical Efficiency:95.5% @ 12V in / 5V 2A out98.5% @ 19V in / 16V 2A out93.3% @ 13.8V in / 5V 7.5A outDimensions: 49 × 24 × 10 mmUsage:Connect input to car battery, 12‑24V battery pack, laptop adapter, etc.Adjust output voltage with a small flathead screwdriver (turn potentiometer counter‑clockwise to increase voltage).Connect load after setting the desired voltage.Applications:Car / vehicle power supply regulationBattery voltage step‑down for portable devicesIndustrial control systemsDIY adjustable power supply12V/24V to 5V/12V/15V conversion
