DC-DC Boost Power Supply Board Synchronous Rectification DC2.7-20V to DC4.5-20V Step Up Constant Voltage and Current Power Board
Features
Input and output up to 20 volts, a wider range of use, far better than the TPS61088.
3.7V/3.2V lithium battery can be boosted, low voltage boost power and classic chip TPS61088 consistent!
Constant voltage constant current function, can achieve booster charging! For example, a 3.7-volt lithium battery is charged with a 12-volt battery.
With synchronous rectification and real output short-circuit protection, such as 3.7 V to 5 V, the conversion efficiency of synchronous rectifier boost is much higher than that of non-synchronous rectification.
The output of this product has a switch. When the output is short circuited, the switch will be turned off and the booster module will stop output. This product can automatically restore output when the short circuit disappears! Rare/excellent/practical feature in booster module!
