ON Semiconductor TL494BDR2 Product Overview

The TL494BDR2 is a versatile and highly integrated Pulse Width Modulation (PWM) controller from ON Semiconductor, a leading supplier in the semiconductor industry. This device is designed to offer precise control of output voltage and current for a wide range of power supply applications, including switched-mode power supplies (SMPS), DC-to-DC converters, and motor control circuits.

The TL494BDR2 incorporates all the functions required for the construction of pulse-width-modulated control circuits in a compact SOIC-16 package. It features two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) comparator, a pulse-steering flip-flop, a 5V precision reference, and output control circuits.

One of the key attributes of the TL494BDR2 is its flexibility. The dual error amplifiers have a common-mode voltage range from -0.3V to VCC - 2V, making it suitable for various feedback control loop configurations. The internal oscillator can be programmed by the user with a single external resistor and capacitor, allowing for a wide frequency range adjustment to suit different application needs.

The dead-time control provides the ability to set the maximum duty cycle range from 0% to 100%, which is crucial for optimizing the efficiency and performance of the power supply. Additionally, the TL494BDR2 offers under-voltage lockout protection and features short-circuit protection to enhance system reliability.

ON Semiconductor's commitment to quality ensures that the TL494BDR2 meets stringent performance criteria, making it a reliable choice for designers looking to implement an efficient power management solution. Whether you are designing a new power supply or upgrading an existing one, the TL494BDR2 PWM controller offers the functionality, performance, and ease of use required for a wide array of power supply designs.
