IRU3021M controller equivalent, 5-bit programmable synchronous buck plus triple ldo controller.
lossless current sensing for both switcher by using the RDS(on) of the high-side power MOSFET as the sensing resistor, an output under-voltage shutdown that detects shor.
requiring multiple on-board regulators. The IRU3021M provides a single chip controller IC for the Vcore, three LDO contr.
