Philips Semiconductors 90W Resonant SMPS with TEA1610 Swing Chip TM Application Note AN99011 Abstract This report describes a 90W Resonant Switched Mode Power Supply ( Res SMPS) for a typical TV or monitor application based upon the TEA1610 Swing Chip TM resonant SMPS contr oller. The power supply is based on the half bridge DC-to-DC r esonant LLC conver ter with zer o-voltage switching. The TEA1610 uses cur rent dr iven frequency control. © Philips Electronics N.V. 1999 All rights are reserved.

Derckx Keywords Swing Chip TEA1610 Resonant SMPS Zero-voltage-switching Number of pages: 27 Date: 99-09-14 Philips Semiconductors 90W Resonant SMPS with TEA1610 Swing Chip TM Application Note AN99011 Summary The Swing Chip TEA1610 contr oller is a monolithic integr ated cir cuit and is implemented on the 650V BCD power logic pr ocess. The IC pr ovides the dr ive function for two discrete power MOSFETs in a half bridge configuration and is a high voltage contr oller for a zer o-voltage switching r esonant conver ter. To guarantee an accurate 50% duty cycle, the oscillator signal passes through a divider before being...
