Description

MB39A136 is 2ch step-down DC/DC converter IC of the current mode N-ch/N-ch synchronous rectification method. It contains the enhanced protection features, and supports the symmetrical-phase method and the ceramic capacitor. MB39A136 realizes rapid response, high efficiency, and low ripple voltage, and its Mar 10, 2014 The L78S series of three-terminal positive regulators is available in TO-220 package and several fixed output voltages, making it useful in a wide range of applications. These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation.
