The TL494CDG from ON Semiconductor is a fixed-frequency, pulse width modulation (PWM) control circuit primarily designed for SWITCHMODE power supply control. This device integrates essential control circuitry, including an on-chip oscillator, error amplifiers, and a 5.0 V reference.
Key electrical specifications include a wide operating voltage range of 7V to 40V and an operating ambient temperature range of 0°C to 70°C. It offers two outputs and operates with a single phase. The device supports both Step-Down and Step-Up/Step-Down functions, utilizing Buck and Push-Pull topologies. Control features include Dead Time Control and Frequency Control, with a maximum duty cycle of 48% and a frequency of 200kHz.
The TL494CDG is housed in a 16-SOIC package, designed for surface mount applications. Its output type is a Transistor Driver, and it features a synchronous rectifier. The part is specified for a maximum power dissipation of 1000 mW at 45°C ambient temperature, with a junction-to-ambient thermal resistance of 80 °C/W.
This controller is suitable for various power supply applications requiring precise PWM control. Its integrated features and robust design make it a versatile component for power management solutions.
