Description
The GS5812B is a synchronous step -down DC/DC
converter that provides wide 3.5V to 16V input
voltage range and 2A continuous load current
capability.
The GS5812B fault protection includes cycle -by-cycle
current limit, UVLO, output overvoltage protection
and thermal shutdown. The adjustable soft-start
function prevents inrush current at turn-on. This
device uses current mode control scheme which
provides  fast  transient  response.  Internal
Compensation  function  reduces  external
compensation components and simplifies the design
process. In shutdown mode, the supply current is
less than 1μA.
The GS5812B is available in a  SOT-23-6 package,
provides good thermal conductance.
