A7322
DC-DC CONVERTER BUCK (STEP-DOWN) 28V, 2A, 500kHZ SYNCHRONOUS
DESCRIPTION
FEATURES
The A7322 is a fully integrated, synchronous rectified Wide input voltage range: 4.2V to 28V
step-down converter that provides wide 4.2V to 28V 2A output current
input voltage range and 2A continuous load current 0.8V reference voltage
capability. The A7322 can operate at PFM mode to Low RDS(ON) integrated power MOSFET
achieve high efficiency and reduce power loss at light
(180/110mΩ)
load. In shutdown mode, the Max supply current is 3μA(Max) shutdown current
about 3μA.
Integrated internal compensation
The A7322 protection function includes cycle-by-cycle High efficiency at light load
current limit, UVLO and thermal shutdown.
