Automatic Boost Constant Current Power Module LTC3780

product description
Maintains a stable output voltage and limits the current over a wide input voltage range. Ideal for general voltage conversion, battery charging, solar, LED, automotive, battery conversion, microcontrollers and electronics.
Synchronous rectification to provide the most efficient power conversion, up to 98%! We tested the following conversion efficiencies: 24V-> 12V1A: 98%, 12V-> 16V1.5A: 85.7%, 8V-> 16V: 76.7%. Buck (buck) efficiency is very high, the converter work in the low heat load, stable operation at higher currents, while maintaining a smaller physical size.
The ideal running electronic battery is off. High efficiency maximizes battery life. The buck / boost function allows the device to run on the full discharge curve of the battery. Under-voltage protection turns off the device when the battery runs out to prevent damage to the lithium and lead-acid batteries.
Input voltage: 5-32V DC, output voltage: 1-30V DC, maximum load: 130W / 10A peak, 80W / 7A continuous (whichever is lower, ampere or watt). The maximum continuous load varies with the input and output voltages and the difference between them does not allow operating temperatures above 140 ° F for long term stable operation.
Size: 77.6x46.5x15mm with External MOSFET, Adjustable Output Voltage, Output Current and Input Undervoltage Protection. 300KHz switching frequency.
The LTC3780 is a high performance buck-boost switching regulator controller with input voltage higher than, lower than or equal to the output voltage. With a wide range of input and output and seamless conversion between operating modes, the LTC3780 is well suited for automotive and battery-powered systems.

Synchronous rectification technology uses a very low on-resistance dedicated power MOSFET instead of rectifier diodes to reduce rectifier losses. Since there is no diode blocking voltage loss, so can greatly improve the efficiency of DC / DC converter. Synchronous rectification technology greatly reduces the switching power supply loss, thereby improving the conversion efficiency and reduce waste heat.
