The LTC7132 is a dual output PolyPhase DC/DC synchronous step-down monolithic regulator with an I2C-based PMBus compliant serial interface. The regulator employs a constant-frequency current mode architecture, together with a unique scheme to provide excellent performance in sub-milliohm DCR applications. The LTC7132 is supported by the LTpowerPlay? software development tool with graphical user interface (GUI).Programmable loop compensation allows the regulator to be compensated digitally. The switching frequency, channel phasing and device address can be programmed both by the digital interface as well as the external configuration resistors. Additionally, parameters can be set via the digital interface and stored in EEPROM. Both outputs have independent power good indicators and FAULT function.The LTC7132 can be configured to operate in discontinuous (pulse-skipping) mode or forced continuous conduction mode. Each channel can deliver up to 25A of loadcurrent; the total current capability will depend on the APPLICATIONS total power dissipations on both channels.POWER CONVERSION Wide VIN Range: 4.5V to 20V VOUT Range: 0.5V to 3.5V (with Ultralow DCR Setting); 0.5V to 5.5V (Typical DCR Setting) Accurate PolyPhase? Current Sharing for Up to 6 Phases Available in a 140-Lead (9mm ? 11.25mm ? 2.22mm) BGA PackageAPPLICATIONS Telecom, Datacom and Storage Systems Industrial and Point-of-Load Applications
