TL494 DIP 41V 250mA PWM Controller IC

The TL494 is a versatile pulse-width modulation (PWM) controller IC designed primarily for power-supply control applications. However, it does not specifically match the 41V 250mA PWM controller IC description as it operates up to 40V and handles output currents up to 200mA per output transistor. Here is a detailed overview of its features and applications:

Features:

• Complete PWM Control Circuitry: Includes two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) comparator, a pulse-steering control flip-flop, and a 5V, 5%-precision regulator.
• Uncommitted Outputs: Capable of sourcing or sinking up to 200mA, suitable for push-pull or single-ended output operations.
• Adjustable Oscillator: Allows for flexible frequency control and can be bypassed for external control.
• Dead-Time Control: Provides a fixed offset for approximately 5% dead time, ensuring efficient switching.
• Operating Voltage Range: From 7V to 40V, making it suitable for various power supply configurations.

Application:

The TL494 is ideal for:

• Power Supplies: Used in AC/DC, isolated, and non-isolated power supplies, including those with power factor correction (PFC).
• Desktop PCs and Servers: Commonly employed in power supplies for these systems.
• Solar Micro-Inverters: Suitable for applications requiring efficient power conversion.
• E-Bikes and Other Portable Devices: Used in power management systems for these devices.

Package Included:

1 x TL494 DIP Pulse-Width Modulation Controller. Please note that the product image is for illustrative purposes only. The actual product may vary slightly in appearance!
