The onsemi TL494BDR2 is a versatile SWITCHMODE™ series DC-DC controller IC, packaged in a 16-SOIC (0.154", 3.90mm Width) for surface mounting. This component is designed for applications requiring precise regulation of positive output voltages in step-down, and step-up/step-down configurations. It features a push-pull topology, enabling efficient power conversion. Key control features include adjustable dead time control and frequency control, with a maximum switching frequency of 200kHz. The TL494BDR2 supports a maximum duty cycle of 48% and operates from a supply voltage range of 7V to 40V. It is equipped with transistor driver outputs and a synchronous rectifier, making it suitable for power supply designs in industries such as industrial automation, consumer electronics, and telecommunications. This device operates across a temperature range of -40°C to 125°C (TJ).
