GENERAL DESCRIPTION
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 control functions to form a flexible and a reliable power supply with a minimum of external components. 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.

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, 40Ω, 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 40µA
• 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
• Under-voltage lockout
• Over-temperature protection.
