Product Description:

Advantages:

All use of imported SMD aluminum electrolytic capacitors, high-power high-Q inductors. Additionally, each a plate have been strictly technical tests, all testing has been completed using a separate anti-static protection bags package. Specially designed two screw holes. Four input and output pads are provided with a pin fixing hole spacing 100mil are integer multiples, convenient volume applications in the product;

Note:

working long hours is recommended for use in less than 2.5A of current, and coupled with the heat sink (10W output above); Since the step-down module, in order to ensure stable output, keep a minimum 1.5V differential.

Voltage Regulator:

Access to power (3-40V), adjust the blue potentiometer knob (clockwise rotation generally boost, buck counterclockwise rotation) and with a multimeter to monitor the output voltage reaches the required voltage.

Wiring:

1. welding, welded directly to the power line input (output) port;

2. solder pins, or pins can be inserted through the lead insertion use in tunnel plate; soldered directly to the PCB after another or add pins.

XL6009:

The XL6009 is a 4A switching current boost (BOOST) module. The module uses high-frequency switching technology XL6009E1 as the core chip, the performance is superior to LM2577. The XL6009 boost module is less expensive and performs better, and the LM2577 module is about to be phased out.
● Ultra-wide input voltage 3V~32V, zui good working voltage range is 5~32V;
● Ultra-wide output voltage 5V~35V;
● Built-in 4A high efficiency MOSFET switch tube, the efficiency is up to 94%; (LM2577 current is only 3A)
● The switching frequency is 400KHz, which can achieve very good results with a small-capacity filter capacitor. The ripple is smaller and the volume is smaller. (LM2577 frequency is only 50KHz)
