TL494 - (SMD/SMT) Pulse width modulation control

TL494 SMD/SMT Pulse Width Modulation (PWM) Control IC

The TL494 is a highly integrated Pulse Width Modulation (PWM) control circuit, designed for efficient power supply management. This single-chip solution offers comprehensive functionality for constructing robust power control systems. Its flexibility allows for precise tailoring of power supply circuitry to meet diverse application requirements. The device features uncommitted outputs, capable of 200mA sink or source current, supporting both single-ended and push-pull operations. An internal regulator provides a stable 5V reference, ensuring reliable performance. With variable dead time control and easy synchronization, the TL494 simplifies complex power designs. It's an ideal choice for engineers seeking a versatile and dependable PWM controller in a compact SMD/SMT package.
