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.
