The Marvell 88PG8318A1-NAE2C000 is a DFN-12 package, Multi-Topology Converter. The Marvell 88PG8318 is a high performance general purpose power managment regulator housed in a 3mm X 4mm DFN-12 package with multiple outputs to power I/O, analog, and core voltage for DSP or CPU applications. It includes one switching regulator and two Low Dropout (LDO) regulators. The switching regulator utilizes a proprietary internally compensated PWM control to regulate the output voltage, which offers fast transient response and minimal external components. The 88PG8318 operates from 2.7V to 5.5V input voltage range. The step-down switching regulator can deliver up to 1.2A output current while the LDOs are capable of sourcing up to 2.5V/150mA and 1.8V/150mA. The switching regulator output voltage can be set to one of eight standard voltages through the VSET resistor. The step-down regulator can also be programmed from 0.72V to 3.63V through the EN/SDI input. The switching frequency is 2MHz (typical), allowing the use of low profile surface mounted inductors and low value capacitors. Input quiescent currents of the 88PG8318 at no loads is 85μA (typical), resulting in high efficiencies at both light and full loads. Other features include internal current limit, soft start, under/over voltage lockout, and thermal shutdown.
