概述 General Description
The TL494 incorporate all the functions
required in the construction of a pulse-width
modulation switching circuit. Designed
primarily for switching power supply control or
DC-DC converters, it offers the systems
engineer the flexibility to tailor control
circuitry to its own application.
TL494具备构建 PWM开关电路要求的所有功能。 该芯
片主要用于设计开关电源控制器和 DC-DC 转换器,
系统工程师可以基于 TL494 轻松定制满足应用要求
的控制电路。
Lead Free: TL494L
Halogen Free: TL494G
