Power plug for the universal mains

INTEGRATED CIRCUITS DATA SHEET TEA1401T Power plug for the universal mains Preliminary specification Supersedes data of 1996 Sep 27 File under Integrated Circuits, IC03 1997 Mar 07 Philips Semiconductors Preliminary specification Power plug for the universal mains FEATURES • Designed for compact power plugs supplying up to 20 W • Integrated high-voltage power DMOS FET 625 V/1 A • Operates from all mains supplies (90 to 280 V AC) • Major design: current regulation at the primary side (no opto-coupler, no secondary electronics) • Low external/peripheral component count • Combines accurate constant-voltage source (for supply) and accurate constant-current source (for charging) in one IC • Foldback feature • Requires simple input filter as a result of good EMC design • Overshoot protection (output voltage) • Protects against under-voltage input, over-current and over-temperature • 20-pin SO medium-power package. QUICK REFERENCE DATA SYMBOL V20 I20 fsw I1 PARAMETER output voltage at pin 20 (DRAIN) current in MOS switch input current at pin 1 (Vin), from the high input voltage. VAT can supply from the low voltage auxiliary winding CONDITIONS 20 times peak value VAT < 10 V (peak) VAT > 10 V (peak); fsw = 90 kHz VAT > 10 V (peak); fsw = 150 kHz VAT > 10 V (peak) Tamb operating ambient temperature MIN. − − 5 − − − − − −20 GENERAL DESCRIPTION TEA1401T The TEA1401T is a Self Oscillating Power Supply (SOPS) controller IC that operates directly from the rectified universal mains.
