DC DC Switching Controllers datasheet and documents for TL494CNE4

TL494CNE4

DC DC Switching Controllers Overview

The TL494CNE4 is a Pulse Width Modulation (PWM) controller manufactured by Texas Instruments, housed in a 16-pin Plastic Dual In-line Package (PDIP). It operates within a supply voltage range of 7 V to 40 V, with a nominal input of 15 V. The device supports switching frequencies up to 300 kHz and delivers an output current of 200 mA. It functions as a voltage-mode switching controller with a maximum duty cycle of 45%. The component is designed for operation across temperatures from 0°C to 70°C.

DC DC Switching Controllers Feature Summary

Integrates complete PWM power control circuitry on a single chip
Offers selectable single-ended or push-pull output configurations
Includes internal 5V reference with 5% tolerance
Features variable dead-time control for switch protection

DC DC Switching Controllers Applications

Computer and peripheral power supplies
Microwave oven control circuits
Consumer electronics power management
Communication and network equipment

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS status. Confirm the package designation matches the required 16-PDIP footprint. Ensure the temperature grade aligns with the 0 to 70°C operational requirement. Cross-reference the manufacturer part number against official Texas Instruments documentation to avoid counterfeit components.

DC DC Switching Controllers Selection Notes

Select this component when a versatile voltage-mode PWM controller is required for standard AC-DC or DC-DC topologies. It is suitable for applications needing both single-ended and push-pull drive capabilities. Consider the PDIP package for through-hole assembly processes. Evaluate thermal requirements against the specified operating temperature range before implementation.

DC DC Switching Controllers Part Context

This part belongs to the TL494 family of PWM controllers, widely used in power supply design. The 'C' variant typically denotes commercial temperature grades, while 'NE4' specifies the PDIP package and environmental compliance. It serves as a foundational control IC for various switching regulator architectures.
