The LX1672 is a highly integrated power supply controller IC featuring two PWM switching regulator stages with an additional onboard linear regulator driver.
The two constant frequency voltagemode PWM phases can be easily configured as a single Bi-Phase high current output, two independently regulated outputs, or as a DDR memory I/O supply with a tracking DDR termination voltage supply. Power loss and noise, due to the ESR of the input capacitors, are minimized by operating each PWM output 180° out of phase. This architecture also minimizes capacitor requirements while maximizing regulator response.KEY
FEATURES◾ Up to Three Independently Regulated Outputs◾ DDR Termination Compliant◾ Bi-phase Current Sharing◾ Outputs As Low As 0.8V Generated From An Internal 1% Reference◾ Multiphase High Current Output Reduces Required Capacitance◾ Integrated High Current MOSFET Drivers◾ 300KHz, 500KHz and 600KHz High Frequency Operation Minimizes External Component Requirements◾ Independent Phase Programmable Soft-Start and Power Sequencing◾ Adjustable Linear Regulator Driver Output◾ No current-sense resistorsAPPLICATIONS/BENEFITS◾ Multi-Output Power Supplies◾ Video Card Power Supplies◾ DDR, VDDQ and Termination Supply◾ PC Peripherals◾ Portable PC Processor and I/O Supply
Functional Equivalent (FE) materials, including Fused Filament Fabrication (FFF) form, assembly, and functionally compatible substitute materials.
