It operates from a 7V to 40V supply and delivers a transistor-driver output with a maximum duty cycle of 45% per output, making it suitable for push-pull and bridge-based designs where dead-time control is critical. The switching frequency spans 1 kHz to 300 kHz, covering the majority of offline and DC-DC converter applications while allowing compact magnetics at the upper end. ## Industrial temperature grade and through-hole package Housed in a 16-pin PDIP (0.300-inch, 7.62 mm body) through-hole package, it is compatible with standard prototyping boards and legacy through-hole assembly lines, and the 0.100-inch pin pitch simplifies manual rework and inspection.","metaTitle":"TL494ING4 PWM Controller, 7V-40V, 1kHz-300kHz, 16-PDIP","metaDescription":"TL494ING4 PWM controller from Texas Instruments.
