INTEGRATED CIRCUITS DATA SHEET TEA1501 Greeny; Green Chip™ Preliminary specification File under Integrated Circuits, IC11 1998 Aug 19 Philips Semiconductors Preliminary specification Greeny; Green Chip™ Features - Direct off-line operation (90 to 276 V AC) - Low external ponent 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. The TEA1501 (Greeny) is the low power member of the Green Chip™ 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_Power Logic750 process and includes the high voltage switching device. Using only 7 functional pins, Greeny contains extensive control functions to form a flexible and a reliable power supply with a minimum of external ponents. Greeny operates in a flyback topology (see Fig.1) with a fixed switching frequency, constant primary peak current control and regulates the output voltage in burst mode. Applications include low power supplies and standby power supplies as used in television, monitor, lighting electronics and domestic appliances with an output power from 0.1 to 3 W. handbook, full pagewidth Vin Vout np Vzener...
