LTC3780 DC-DC Automatic Step Up Down Buck Boost Module Vehicle Laptop Computer Power Supply 14A

LTC3780 DC-DC Automatic Step Up Down Buck Boost Module Vehicle Laptop Computer Power Supply 14A

Description:
This module is a high-efficiency automatic buck-boost regulator module, using LTC3780 as the main control chip. Input voltage can be higher than output voltage or lower than the output voltage, and the output voltage remains stable. For example, if the output is set to 12V, when the input voltage changes between 5 and 32V, the output voltage will remain unchanged at 12V.

This module has complete protection functions and can be widely used in laptop power supplies, vehicle power supplies, industrial control power supplies, model aircraft power supplies, embedded systems, etc.

Features:
- Wide input voltage range: 5~32V
- Output voltage: It can be arbitrarily adjusted between 2~24V, or fixed output voltage type (any choice between 2~24V), please specify when purchasing. The default delivery is adjustable.
- Continuous output current: 12A, maximum 14A (input 14V, output 12V).
- Using advanced synchronous rectification technology, conversion efficiency can reach up to 98%
- Working frequency: 200KHz
- Output over-current and short-circuit protection, even if the output terminal is short-circuited, the circuit will automatically protect
- 15A fuse is used at the input, plus one more level of safety protection measures
- Chip with over-temperature protection, automatically stop working when over temperature
- Input under-voltage protection, stop working when the input voltage is lower than 4.5V
- No input reverse connection protection, input and output reverse connection will cause the module burnt out
- Soft start function to ensure no overshoot voltage during power-on
- Enable terminal can directly control the switch of output voltage, and the output voltage can be turned off by directly grounding, and the module enters sleep mode. Do not connect (floating) to turn on the output.
- Both input and output terminals adopt LC filtering, and use large-capacity ceramic capacitors and high-frequency low-resistance electrolytic capacitors to ensure extremely low input and output ripple. When inputting 14V, outputting 12V 10A, the ripple ≤30mVp-p. Especially under vehicle application conditions, it will not interfere with other devices
- Full load temperature rise: 50℃, heat sink has been installed on delivery to enhance heat dissipation
- Industrial grade working temperature range: -45 to 85℃
- Dimensions: 85 x 48 x 25mm (LxWxH)
- Connection method: terminal type

Typical Output Current & Power (ambient temperature 25℃, open to natural air cooling):


Application Examples:
- Used for power supply of vehicle equipment. Convert unstable and noisy 12V in a car into a stable and clean 12V output to power on-board MP3, MP4, GPS, media players, mobile phones, on-board computers and other devices.
- DIY an adjustable DC power supply. Connect a 12V power supply at the input, and output voltage can be adjusted freely between 0.8 to 24V. It can be used as a power supply for maintenance and various laboratory power supplies. Easy to use, cost-effective, suitable for all kinds of electronic enthusiasts.
- Used for power supply of car laptop. Boost unstable and noisy 12V in a car to the voltage required by notebook computer, such as 16V, 19V, and 20V.

Precautions:
- Before purchasing, please read the information we provide carefully.
- Electronic DIY requires a certain degree of professional knowledge and hands-on ability. Please be familiar with the module parameters and wiring methods, etc., and operate with caution to avoid damage caused by human factors such as reverse connection of input and output polarity.
