Package
P-DIP-18-4
The Siemens Power Hybrid SPH 4692 contains the SMPS IC TDA 4605-3 as well as the SIEMENS
POWER MOSFET in a P-DIP-18 package.
The IC TDA 4605-3 controls the MOS-power transistor and performs all necessary control and
protection functions in free running flyback converters. Because of the fact that a wide load range
is achieved, this IC is applicable for consumer as well as industrial power supplies.
