Flash charging high current to protect the battery

The TPS65552A offers three forms of protection. The TPS65552A uses MAX ON TIME, OVER VDS, and THERMAL shutdown. For example, the MAX ON TIME protection prevents the controller from trying to pull too much current from a low battery that cannot supply enough current and thus never reaches the target peak current. All three protection functions ...

Can a flash Charger charge a high-current battery?

A low-profile, high-current, and low-loss inductor is another major hindrance for high-current battery charging. The flash charger is a system-level solution.
