Description

Mini DC-DC 9V/12V to 5V 4A Step Down Power Supply Module Voltage Buck Converter Conversion efficiency Adjustable 98%

9V 12V to 5V:Features:1. Using high-quality materials, the quality is guaranteed2. Luxurious materials, 2 oz copper clad + immersion gold process3. Ultra-high conversion efficiency, up to 92.7~98% (up to 98% at 10V input)4. The appearance of the product is exquisite and small5. Wide applicationParameter:Input voltage: 6.5~16VOutput voltage: 5VOutput current: 0~4AVoltage accuracy; <1%Linear adjustment rate: <0.5%Load regulation rate: <1%Output ripple noise: <20mVConversion efficiency: 92~97% at 12V inputStatic power consumption: <500uAWorking environment: -40℃~85℃Instructions for use of the EN pin: The default high level, with its own pull-up resistor, when EN is grounded, the module turns off the output.Note:Do not use this power module for automotive circuits. When the automotive generator starts, the voltage fluctuates greatly, and it is easy to overvoltage and break down the chip!Package Included:1* Step-down module

4.5-16V to 3.3V 5V:Features:1. Using high-quality materials, the quality is guaranteed2. Luxurious materials, 2 oz copper clad + immersion gold process3. Ultra-high conversion efficiency4. The appearance of the product is exquisite and small5. Wide applicationParameter:Input voltage: 4.5B~16VOutput voltage: 3.3V/5.2VOutput current: 0~4AVoltage accuracy; <1%Linear adjustment rate: <0.5%Load regulation rate: <1%Output ripple noise: <20mVConversion efficiency: >85%, up to 98%Static power consumption: <500uAWorking environment: -40℃~85℃There are two preset voltages, the default output is 5.2V (when charging electronic products such as mobile phones, the line loss can be compensated to achieve a larger charging current), and the output voltage can be adjusted to 3.3V by disconnecting the pad with a soldering iron. Lead out the EN control pin, the default high level has output, and there is no output when low level. Lead out the FB pin, and the output voltage can be changed by changing the FB divider resistor.Temperature test situation: input 12V, output 5.2V4A, room temperature is 30°, the module is suspended in the air (only fixed by the alligator clips at the input and output ends), after 2 hours of operation, the temperature measuring gun measures multiple times, and the maximum temperature does not exceed 75°. In practical applications, the GND pin can also be welded with other copper foils to dissipate heat.Note:Do not use this power module for automotive circuits. When the automotive generator starts, the voltage fluctuates greatly, and it is easy to overvoltage and break down the chip!Package Included:1* Step-down module
