TEA1504

INTEGRATED CIRCUITS DATA SHEET TEA1504 GreenChip™ SMPS control IC Preliminary specification Supersedes data of 1998 Mar 17 File under Integrated Circuits, IC11 1999 Dec 07 Philips Semiconductors Preliminary specification GreenChip™ SMPS control IC FEATURES Distinctive features High level of integration reduces the number of components by up to 50 compared to power supply using discrete components On/off functional switch replaces expensive mains switch Direct off-line operation (90 to 276 V AC) 5% accurate on-chip oscillator. Green features Low power consumption in off-mode (<100 mW) Fast and efficient on-chip start-up current source Burst mode standby (<2 W) for overall improved system efficiency Low power operation mode with lower frequency reduces switching losses Low Overcurrent Protection (OCP) level. Protection features Demagnetization protection Cycle-by-cycle current limitation with programmable current trip level Overvoltage protection Overtemperature protection Safe-restart mode with reduced power for system fault conditions. Highly versatile Usable in buck and flyback topology Interfaces both primary and secondary side feedback. ORDERING INFORMATION PACKAGE TYPE NUMBER NAME TEA1504 DIP14 DESCRIPTION plastic dual in-line package; 14 leads (300 mil) GENERAL DESCRIPTION TEA1504 The GreenChip™ TEA1504 is intended for off-line 90 to 276 V (AC) power supply applications. It is one of a family of high voltage ICs integrating both analo...
