FEATURES
Distinctive features
• High level of integration reduces the number of
components by up to 50 compared to power supply
using discrete components
• On/off functional switch replaces expensive mains
switch
• Direct off-line operation (90 to 276 V AC)
• 5% accurate on-chip oscillator.
Green features
• Low power consumption in off-mode (<100 mW)
• Fast and efficient on-chip start-up current source
• Burst mode standby (<2 W) for overall improved system
efficiency
• Low power operation mode with lower frequency
reduces switching losses
• Low Overcurrent Protection (OCP) level.
Protection features
• Demagnetization protection
• Cycle-by-cycle current limitation with programmable
current trip level
• Overvoltage protection
• Overtemperature protection
• Safe-restart mode with reduced power for system fault
conditions.
GENERAL DESCRIPTION
The GreenChip™ TEA1504 is intended for off-line
90 to 276 V (AC) power supply applications. It is one of a
family of high voltage ICs integrating both analog and
digital circuit functions for controlling a switched mode
power supply (SMPS). Its functions include integrated high
voltage start-up current source, voltage Pulse Width Mode
(PWM) control, 5% accurate oscillator, band-gap derived
reference voltages, comprehensive fault protection and
leading edge blanking. Its high level of integration allows
power supplies to be cost effective, compact, lightweight,
highly efficient, more reliable, and simple to design.
Efficient green features permit very low power operation
modes, and an innovative on/off function allows an
expensive mains switch to be replaced with a low-cost
functional switch.
THE GREENCHIP™ FAMILY
The GreenChip™ family of ICs are fully integrated with
most common PWM functions such as error amplifier,
oscillator, bias current generator and band-gap based
reference voltage circuits. The high level of integration
allows easy and cost effective power supply design.
The ICs are made by a Philips proprietary high voltage
BCDMOS process which produces low voltage circuit
devices with inputs that are able to withstand up to 720 V.
Highly versatile
• Usable in buck and flyback topology
• Interfaces both primary and secondary side feedback.
