封装:DIP-16
TL494 开关稳压器的概述:
The TL494 is a voltage mode pulse width modulation switching regulator control circuit designed primarily for power supply control.
The TL494 consists of a reference voltage circuit,two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) comparator, a pulse-steering control flip-flop, and an output control circuit. The precision of voltage reference (VREF) is improved up to ±1% through trimming and this provides a better output voltage regulation. The TL494 provides for push pull or single-ended output operation, which can be selected through the output control.
The TL494 is available in standard packages of DIP-16 and SOP-16.
