TEA1501
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 , 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 A
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.
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.
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.
