Philips TEA1504 Data Sheet
Summary
The TEA1504 GreenChip is a high-integration SMPS control IC designed for reliable off-line power supply applications (90 to 276 V AC). It significantly simplifies power supply design by integrating essential functions—including PWM control, an internal oscillator, and startup current source—to create compact and efficient Switched Mode Power Supplies. This manual details the device’s pin configuration, functional blocks, and operation principles. Ideal for electronics engineers creating cost-effective, low-power consumption, and highly reliable power management systems requiring multiple sophisticated protection features.
