15-24V to 12V 12A DC-DC Buck Converter Step Down

The DFRobot step-down converter turns 15 to 24 V into stable 12 V with up to 12 A, for example for several servos and motors, LED lighting or the electronics in robots and drones. Efficiency is above 95 % at 24 V input, ripple below 50 mV. The small module has castellated solder pads and a thermal pad on the underside which, soldered to a large copper area, dissipates the heat.

Features:

• Input 15 to 24 V DC, output 12 V ±1 %, up to 12 A
• Efficiency above 95 % at 24 V input and 1 to 12 A, ripple below 50 mV
• Overtemperature protection at 125 °C and short-circuit protection on the output
• EN open: output on; EN to GND: output off; can be controlled from a microcontroller pin via 1 kΩ in series
• AGND as single ground point for control by a microcontroller
• According to DFRobot PGOOD signals a correct output voltage with HIGH (5 V), a fault or short circuit with LOW (0 V)
• Quiescent current below 3 mA with EN open, below 3 µA with EN to GND
• Castellated solder pads VIN, GND, VOUT, EN, AGND, PGOOD and thermal pad on the underside

Application Examples:

• Supplying several servos, motors and sensors in robots
• On-board electronics in drones
• High-power LED lighting
• Auxiliary voltage in vehicle electronics
