Add To BomTL494CD General Description
The TL494CD is a pulse-width modulation (PWM) controller IC specifically designed for controlling power supplies. It features two error amplifiers, an adjustable oscillator, and a dead-time control comparator for achieving high efficiency in power conversion applications. The TL494CD has a wide input voltage range of 7V to 40V and can drive power mosfets directly, making it suitable for both low and high power applications. It can provide a maximum duty cycle of 100% and a switching frequency up to 500 kHz, allowing for precise control of power output.This IC also includes a soft-start function for preventing overshoot and power surges during start-up, as well as a shutdown pin for disabling the device when needed. It comes in a SOIC-16 package and operates over a temperature range of -40°C to 85°C.
