„ GENERAL DESCRIPTION
The LSP5502 is a monolithic synchronous buck
regulator. The device integrates 120mΩ MOSFETS
that provide 2A continuous load current over a wide
operating input voltage of 4.5V to 27V. Current mode
control provides fast transient response and
cycle-by-cycle current limit.
An adjustable soft-start prevents inrush current at turn
on. In shutdown mode, the supply current drops
below 1µA.
This device, available in an 8-pin SOP package,
provides a very compact system solution with minimal
reliance on external components.
