Product Description

This module is a highly efficient automatic buck regulator module, using Linear's LTC3780 United States as the main chip. The input voltage is higher than the output voltage can also be lower than the output voltage, and the output voltage is maintained constant. For example, set the output to 12V, then the input voltage varies between 5 ~ 32V, output voltage at 12V constant. The module has the perfect protection function, and can be widely used in notebook power, automotive power, industrial power model aircraft power, embedded systems and so on.

Features

Wide input voltage range: 5 ~ 32V
Output voltage: can be adjusted between 2 ~ 24V, can also choose a fixed voltage (2 to choose between 24V), please indicate the time of purchase. Default shipping is adjustable
Continuous output current: 12A, maximum 14A (input 14V, output 12V).
The use of advanced synchronous rectification technology, conversion efficiency up to 98%
Operating frequency: 200KHz
Output over-current, short circuit protection, output short circuit is not afraid even end, the circuit will automatically protect
Inputs with 15A fuse, Cadogan a security protection measures

Chip with overheat protection, over-temperature automatically stop working
Input undervoltage protection, to stop working when the input voltage is lower than 4.5V
No input reverse polarity protection, input and output reversed will burn
Soft-start function, make sure that the power process without overshoot voltage
Enabled client can directly control the output voltage of the switch, straightforward ground to close the output voltage, the module goes into sleep mode. Not connected (floating) output opens.

Input and output LC filters are used, and the use of large-capacity ceramic capacitors and Taiwan high-frequency low-impedance electrolytic capacitors, ensuring very low input and output ripple. Input 14V, output 12V10A Ripple ≤30mVp-p. Especially in the automotive application conditions, it does not interfere with other devices
Full load temperature rise: 50 ℃, shipping has been installed heat sink, to enhance heat dissipation

Industrial operating temperature range: -45 ~ + 85 ℃
Volume: 85X48X25mm (length X
