2A 20V Synchronous Rectified Step-Down Converte
DATASHEET
TD1482A
General Description
Features
The TD1482A is a monolithic pulse-width-modulated (PWM)
synchronous step-down switch mode regulator with two
internal power MOSFETs. It achieves 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 package, provides a
very compact solution with minimal external components.
