Rochester Electronics TL494ID Environmental and export classification status description
The TL494ID is a pulse-width modulation (PWM) controller integrated circuit designed for power supply applications. It provides the necessary control signals for regulating the output voltage of a switching power supply. Functions: - Provides precision regulation of the output voltage. - Generates adjustable duty cycle PWM signals. - Offers oscillator, error amplifier, and output drivers. - Incorporates features like soft start, shutdown control, and cycle-by-cycle current limiting. Applications: The TL494ID is commonly used in various power supply applications, including: 1. Switching power supplies 2. Battery chargers 3. DC-DC converters 4. Uninterruptible Power Supplies (UPS) Alternative Parts: If the TL494ID is not available or suitable for your specific requirements, you can consider the following alternative PWM controllers: 1. UC3842 from Texas Instruments 2. SG3525 from Microchip Technology 3. GS4911B from ON Semiconductor Embedded Modules: The TL494ID is commonly used alongside other circuit components to form complete power supply modules. These modules may include: 1. MOSFETs or transistors to control the switching operation. 2. Inductors and capacitors for filtering and energy storage. 3. Voltage feedback circuitry for regulation. 4. Diodes for rectification. Q&A: 1. Q: How does the TL494ID control the output voltage in a power supply? A: The TL494ID uses feedback from the output voltage to adjust the duty cycle of the PWM signals, which regulates the output voltage. 2. Q: Can the TL494ID be used in battery charging applications? A: Yes, the TL494ID is suitable for battery charger designs, allowing precise control of the charging voltage and current. 3. Q: What is the purpose of the soft-start feature in the TL494ID? A: The soft-start feature gradually ramps up the output voltage during startup, preventing excessive current or voltage surges that could damage the system. 4. Q: How does the TL494ID provide cycle-by-cycle current limiting? A: The TL494ID continuously monitors the current flowing through the power switches and limits it on a per-cycle basis, protecting the power supply from overload conditions. 5. Q: Are there any specific precautions to consider when using the TL494ID? A: The TL494ID requires careful consideration of component selection, layout design, and thermal management to ensure proper operation and reliability. It is recommended to refer to the datasheet for detailed guidelines.
