TEA1504 - GreenChip SMPS control IC

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. 

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.

Highly versatile

• Usable in buck and flyback topology

• Interfaces both primary and secondary side feedback.
