Part Number: TH2267.1
Description: PWM Controller IC
Package: SO-8 Pin Package
Manufacturer: Melexis ( Microelectronic Integrated Systems )
TH2267.1 is an application specific device for the control of the primary side of a switched mode charger. The controlled variable is transferred by an additional winding from the secondary to the primary side. Additional reference for the primary control function and the power supply are derived from the inclueded bandgap reference. For the specific regulation characteristic resuting in driver switch-on and switch-off, current- and voltage monitoring with time constant and fixed characteristic curve are inclueded.
