点击图片查看原图General Description
The TD1670 is a monolithic, step-down, switch mode converter
with a built-in power MOSFET. It achieves a 1.2A peak-output
current over input supply 10V-60V with excellent load and line
regulation. Current-mode operation provides a fast transient
response and eases loop stabilization. Fault condition
protections include cycle-by-cycle current limiting and thermal
shutdown.
The TD1670 requires a minimal number of readily-available
external components.
The TD1670 is available in a ESOP-8 package.
