2 / 20 page 2001 Apr 25 2 Philips Semiconductors Product specification Zero-voltage-switching resonant converter controller TEA1610P; TEA1610T FEATURES • Integrated high voltage level-shift function • Integrated high voltage bootstrap diode • Transconductance error amplifier for ultra high-ohmic regulation feedback • Latched shut-down circuit for overcurrent and overvoltage protection • Low start-up current (green function) • Adjustable minimum and maximum frequencies • Adjustable dead time • Undervoltage lockout. GENERAL DESCRIPTION The TEA1610 is a monolithic integrated circuit implemented in a high-voltage DMOS process. The circuit is a high voltage controller for a zero-voltage switching resonant converter. The IC provides the drive function for two discrete power MOSFETs in a half-bridge configuration. It also includes a level-shift circuit, an oscillator with accurately-programmable frequency range, a latched shut-down function and a transconductance error amplifier. To guarantee an accurate 50% switching duty factor, the oscillator signal passes through a divide-by-two flip-flop before being fed to the output drivers. The circuit is very flexible and enables a broad range of applications for different mains voltages. APPLICATIONS • TV and monitor power supplies • High voltage power supplies.
