  • Publication number: 20230121953
    Abstract: Apparatuses and methods for regulating a system rail voltage of a battery charger is described. An integrated circuit can be configured to detect a condition that requires an activation of a trickle charge mode of a battery charger. The integrated circuit can, in response to the detection, set a reference voltage to an intermediate voltage level. The reference voltage can control a system rail voltage of the battery charger, and the intermediate voltage level can be greater than a minimum of the system rail voltage. The integrated circuit can reduce the reference voltage from the intermediate voltage level to the minimum system rail voltage to regulate the system rail voltage at a predefined rate.

  • Publication number: 20110221478
    Abstract: Multiple characteristics of a DC-DC converter, such as its mode of operation (e.g., either forced continuous conduction mode, or discontinuous conduction mode), and an operational parameter (such as the dead-time between switching times of the output switching devices (upper and lower MOSFETs) of the converter, whose associated driver integrated circuit has a pin usage that leaves only a single pin available for auxiliary purposes, are programmed by a single pin-based digital and analog information extracting circuit that couples both digital information and analog information within the same control signal to the driver IC by way of only the one available pin.
