The TL494MJB from Texas Instruments is a versatile pulse-width-modulation (PWM) control circuit. It offers complete PWM power-control circuitry with uncommitted outputs capable of 200mA sink or source current. This device allows for flexible output control, enabling single-ended or push-pull operation.
Key features include internal circuitry that prohibits double pulsing at either output and variable dead time control. An internal regulator provides a stable 5V reference supply with a 5% tolerance. The circuit architecture is designed for easy synchronization.
This PWM controller operates within a voltage range of 7V to 40V and supports a maximum frequency of 300kHz. It is available in a 16-pin CDIP package, suitable for through-hole mounting. The operating temperature range is specified from -40°C to 85°C for one variant and 0°C to 70°C for another.
Applications for the TL494MJB include desktop PCs, microwave ovens, and various power supplies such as AC/DC, isolated, and those with PFC (>90W), as well as server PSUs.
The TL494MJB operates from 7 V to 40 V input.
