General Description

The TD1484A is a monolithic pulse-width-modulated (PWM)
synchronous step-down switch mode regulator with two
internal power MOSFETs. It achieves 3.2A continuous output
current over a wide input supply range with excellent load
and line regulation. Current mode operation provides fast
transient response and eases loop stabilization. Fault
condition protection includes cycle-by-cycle current limit and
thermal shutdown.
This device, available in
an SOP8-PP package, provides
a very compact solution with minimal external components.
