Overview

The LTM4632 is an ultrathin triple output step-down μModule (power module) regulator to provide complete power solution for DDR-QDR4 SRAM. Operating from a 3.6 to 15V input voltage, the LTM4632 supports two ±3A output rails, both sink and source capable, for VDDQ and VTT, plus a 10mA low noise reference VTTR output. Both VTT and VTTR track and are equal to VDDQ/2. Housed in a 6.25mm×6.25mm×1.82mm LGA and 6.25mm×6.25mm×2.42mm BGA packages, the LTM4632 includes the switching controller, power FETs, inductors and support components. Alternatively, the power module can also be configured as a two phase single ±6A output VTT. Only a few ceramic input and output capacitors are needed to complete the design. The LTM4632 supports selectable Burst Mode operation (CH1 only) and output voltage tracking for supply rail sequencing. Its high switching frequency and current mode control enable a very fast transient response to line and load changes without sacrificing stability. Fault protection features include overvoltage input, overcurrent and overtemperature protection. The LTM4632 is available with SnPb (BGA) or RoHS compliant terminal finish
