Description:
This DCDC
converter module is a buck (stepdown) converter combined with a boost
(stepup) 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 boostbuck module can step up or step
down voltage and maintain a stable output voltage.
It supports input overcurrent protection, input
undervoltage protection and MOS input antireverse 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&blue light on when constant current charging, blue light on only when constant voltage charging, blue&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)
