A7320
DC-DC CONVERTER/ BUCK (STEP-DOWN)
2A, 23V SYNCHRONOUS RECTIFIED STEP-DOWN CONVERTER
DESCRIPTION
The A7320 is a monolithic synchronous buck
regulator. The device integrates 130mΩ
MOSFETS that provide 2A continuous load
current over a wide operating input voltage of
4.75V to 23V. Current mode control provides
fast transient response and cycle-by-cycle
current limit.
An adjustable soft-start prevents inrush current
at turn-on. Shutdown mode drops the supply
current to 1μA.
This device, available in an 8-pin SOP package,
provides a very compact system solution with
minimal reliance on external components.
A7320 is available in SOP8 Package
