TEA1501

INTEGRATED CIRCUITS DATA SHEET TEA1501 Greeny; GreenChip™ Preliminary specification File under Integrated Circuits, IC11 1998 Aug 19 Philips Semiconductors Preliminary specification Greeny; GreenChip™ FEATURES Direct off-line operation (90 to 276 V AC) Low external component count Integrated high voltage startup current source for a fast startup within 0.25 s Integrated power switch: 650 V, 40 Ω, 0.25 A Programmable primary peak current Data transfer from isolated secondary side to non-isolated primary side via the transformer On/Off function replaces expensive mains switch by a functional switch. Green features Low current consumption in Off mode, typical 40 µA Efficient burst mode operation, for 0.1 to 3 W output power. Protection features Cycle-by-cycle current control with programmable primary peak current Over-voltage protection BASIC FLYBACK CONFIGURATION GENERAL DESCRIPTION Under-voltage lockout Over-temperature protection. TEA1501 The TEA1501 (Greeny) is the low power member of the GreenChip™ family and is especially designed for standby switched mode power supply applications. Greeny incorporates all the necessary functions for an efficient and low cost power supply for 90 to 276 V AC universal input. Greeny is a monolithic integrated circuit and is available in a DIP8 package. The design is made in the BCD_PowerLogic750 process and includes the high voltage switching device. Using only 7 functional pins, Greeny contains extensive contr...
