TDA4916GG

SMPS-IC with MOSFET Driver Output TDA 4916 GG Features High clock frequency Low current drain High reference accuracy All monitoring functions P-DSO-24-1 Type TDA 4916 GG Ordering Code Q67000-A9230 Package P-DSO-24-1 Functional Description and Application The general-purpose single-ended switch-mode power supply device for the direct control of SIPMOS power transistors incorporates both digital and analog functions. These are required for the construction of high-quality flyback, forward and choke converters. The device can be likewise used for transformer-less voltage multipliers and variable-speed motors. Faults occurring during operation of the switch-mode power supply are detected by comparators integrated in the device which initiate protective functions. In addition, pairs of power supplies can be synchronized in antiphase. In-phase or antiphase synchronization is possible when more than two power supplies are involved.
