MA5624
MA5624 is 30V Synchronous Buck Controller manufactured by Major Power Technology.
DESCRIPTION
The MA5624 is a synchronous buck controller. The device need externals high side and external low side power MOSFETs, and provides 5A of continuous load current and a wide input voltage of 8V to 30V. Current mode control provides fast transient response and cycle-by-cycle current limit.
An internal soft-start prevents inrush current at turn-on, this device available in small TDFN-23L (4x4) package, provides a very pact solution with minimal external ponents.
