A voltage/current regulator and method for battery charging |
摘要 |
A voltage/current regulator regulates charging of a rechargeable battery in a portable apparatus that includes a transistor and a controller means coupled to the transistor for controlling the charging current to the battery. The controller determines the power dissipation in the transistor of the regulator. If the power dissipation is above a maximum allowed power dissipation, the controller decreases the charging current by a particular current step. Otherwise, the controller determines if the power dissipation will exceed the maximum allowed power dissipation if the charging current is increased by the current step. If not, the controller increases the charging current by the current step. |
