DC-DC 100W Constant Current Boost Step-Up Module
Description:
This product is based on high-power car laptop power supply constant current regulator increased the charge cutoff voltage regulation;
This has the following advantages:
1, when used as a car laptop power supply increases the output overcurrent, overload protection, and thus more secure.
2, a high-power LED driver, battery charging use, provides a boost constant current drive mode, to drive to the lower supply voltage and low voltage power supply led higher voltage to the high-voltage battery charging possible .
Feature:
Module Properties: non-isolated boost non-synchronous rectification module CC CV constant voltage charging module
Input voltage: DC 10-33V / 10A (max)
Output voltage: DC 11-35V default shipping voltage 19V current 1A (NOTE: Input voltage higher than the output voltage, can not buck)
Output Current: Input 12V, output 19V, 5A max
Output Power: 95W Maximum input support course (minimum input power output power to 1.2-fold)
Easy to drive 65W 90W dual-core notebooks include
Laptop module temperature with a 12V battery with ordinary 19V 3.42A of about 45 degrees
Conversion efficiency: 94% (input 12V output 19V 2.5A when measured) (Reference)
Operating temperature: Industrial grade (-40 ℃ to + 85 ℃) (ambient temperature exceeds 40 degrees, lower power use, or plus fan)
Module dimensions: length 65mm x width 34mm (including heat sink 56.5mm) x 24mm high
Constant current range: 0.3-4A (adjustment)
Turn lamp current: constant current value x (0.1), turn the lamp current constant current value linkage, such as constant value 3A, turn the lamp current is set to a constant current of 0.1 times (0.1 x 3A = 0.3A), when the constant when the current value is adjusted to 2A, then turn the lamp current constant current of 0.1 times (0.1 x 2A = 0.2A).
Conversion efficiency: up to about 90% (efficiency and input and output voltage, current, pressure related
Precautions:
1, the output voltage is lower than the input voltage is not constant because the booster circuit closed even after the boost, the output voltage will be equal to the input voltage.
2, the output power will be lower than the input power, because the efficiency of any module can not reach or exceed 100%; in order to ensure the output, be sure to ensure that the input power margin sufficient because the switching power supply work in the off state, the instant impact current is much higher than the current working.
3, since this module power is larger, so the input current is also large, so the input and output leads to possible rough diameter, length should be as short as possible, the input voltage of the input and output wiring is on the module test us seat voltage prevail, irrespective of line loss.
