{"title":"Pololu D42V55F24 24V 4A Step-Down Voltage Regulator","handle":"pololu-step-down-voltage-regulator-24v-4a","url":"/products/pololu-step-down-voltage-regulator-24v-4a","description":"The Pololu D42V55F24 is a compact synchronous step-down, or buck, switching regulator for converting a higher DC input voltage down to a regulated 24 V output. It is designed for efficient power conversion in applications where a linear regulator would waste too much energy as heat.The board accepts input voltages from 24 V up to 60 V and can deliver up to 4 A, with typical continuous output current depending on input voltage and thermal conditions. Efficiency is around 90% to 95%, varying with load, input and output voltage.Protection and control features include input reverse-voltage protection, over-current protection, thermal shutdown and soft-start to limit inrush current. The module is prototyping-friendly, with duplicated power rails, six 0.1″ grid-compatible connections and three mounting holes for #2 or M2 screws.Features:Regulator type: Compact synchronous step-down (buck) switching regulatorEfficient conversion: Reduces a higher input voltage to a lower output voltage while increasing available currentInput protection: Includes input reverse-voltage protectionOver-current protection: Includes over-current protectionThermal protection: Includes thermal shutdownSoft-start: Includes soft-start to limit inrush currentMounting: Includes three mounting holes for #2 or M2 screwsPrototyping connections: Includes six 0.1″ grid-compatible connections (VIN, VOUT, GND, VRP, EN, PG)Power rails: Includes duplicated power rails for easy prototypingSpecifications:Model: Pololu D42V55F24Input voltage: 24 V up to 60 VOutput voltage: 24 VOutput current: up to 4 ATypical continuous output current: 2.5 A to 5 A, depending on input voltage and thermal conditionsEfficiency: around 90% to 95%, varying with load, input, and output voltageSwitching frequency: approximately a 400 kHz switching frequency under heavy loadsQuiescent current: very low quiescent current at no loadDimensions: 1″ × 1″ × ~0.355″ (25.4 × 25.4 × 9 mm)Mounting holes: three mounting holes for #2 or M2 screwsConnections: six 0.1″ grid-compatible connections (VIN, VOUT, GND, VRP, EN, PG)Power rails: duplicated power rails for easy prototypingUse this regulator for 24 V rails in robotics, automation, LED systems and other DC power projects where efficient conversion from a higher supply is needed.","vendor":"SparkFun","product_type":"Voltage Regulator","in_stock":true,"options":[],"variants":[{"id":16081,"title":"Default Title","sku":"SF-COM-29787","mpn":"COM-29787","price":73.75,"on_sale":false,"in_stock":true,"available_quantity":11}]}
