DC-DC CONVERTER BUCK (STEP-DOWN)
28V, 3A, 500kHz, SYNCHRONOUS
DESCRIPTION
The A7332 integrated synchronous rectified stepdown converter that provides wide 4.2V to 28V input voltage range and 3A continuous load current capability. The A7332 operates at PFM mode to achieve high efficiency and reduce power loss at light load. In shutdown mode, the Max supply current is about 3μA.
The A7332 has protection function includes cycleby-cycle current limit, UVLO and thermal shutdown. Internal soft-start prevents inrush current at fast power-on. The A7332 uses slope pensated current mode control which provides fast load transient response. Internal...
