DESCRIPTION
FEATURES
The A7332 is a synchronous step-down DC/DC
converter that provides wide 4.2V to 30V input
voltage range and 3A continuous load current
capability. At light load condition, the A7332 can
operate at power saving mode to support high
efficiency and reduce power loss.
The A7332 fault protection includes cycle-by-cycle
current limit, UVLO and thermal shutdown. Besides,
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
compensator components and simplifies the design
process. In shutdown mode, the supply current is
about 3μA.
The A7332 is available in PSOP8 package.
