35W 3A DC-DC Step-Up/Down Converter, 5V-30V to 0.5V-30V

<div>Welcome to our store! We hope you have a wonderful shopping experience!</div>

<ul><li>This DC-DC 
converter module is a buck (step-down) converter combined with a boost 
(step-up) converter, of which output voltage can be lower or higher than 
the input. It features small size, high power, 
high efficiency and stable performance. It would maintain output voltage 
stability when input voltage is higher, lower than output 
voltage. 
Features: 
This boost/buck module can step up or step 
down voltage and maintain a stable output voltage. 
It supports input over-current protection, input 
under-voltage protection and MOS input anti-reverse protection. 
It has quite low output ripple voltage 
, for 
example, 20mV when output is 12V 3A, which is great for powering speaker, audio 
amplifier, artificial circuit, etc. 
Input 5V to 30V and it can charge storage battery, lithium battery, AA rechargeable battery, or adjust constant current LED brightness. 
Red&amp;blue light on when constant current charging, blue light on only when constant voltage charging, blue&amp;green light on when almost fully charged, green light on only when fully charged. 
Specifications: 
Input Voltage: 5V~30V 
Output Voltage: 0.5V~30V 
Output Current: 3A (or 4A if enhance heat dissipation) 
Output Power: 35W (or 60W if enhance heat dissipation) 
Output Ripple Voltage 
: 20mV (at 12V 3A output) 
Conversion Efficiency: 87~91%(step up); 87~89%(step down) 
Input Over-current Protection: 10A fuse 
Input Anti-reverse Protection: High efficiency MOS 
Input Under-voltage Protection: Yes 
Output Over-current Protection: Yes 
Frequency: 180kHz 
Size: 69*28*21mm / 2.71*1.1*0.82" 
Package Includes: 
1 x Module</li></ul>
