General Description
TD1432 is a monolithic asynchronous buck regulator. The
device provides 2A of continuous load current over a wide
input voltage of 9V to 40V. It uses current mode control to
regulator the output voltage and provides fast transient
response.
Requiring a minimum number of external components, these
regulators are simple to use and include internal frequency
compensation, and a fixed-frequency oscillator. Anti-ring
function is to reduce the influence of EMI.
This device, available in a SOP-8 package, provides a very
compact system solution with minimal reliance on external
components.
