LTM4632IY#PBF

LTM®4632 is a triple output step-down µModule® (power module) regulator. This supports two ±3A output rails, both sink and source capable, for VDDQ and VTT, plus a 10mA low noise reference VTTR output. Includes the switching controller, power FETs, inductors and support components. Alternatively, this 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. It 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. Applications are DDR memory power supply, general purpose point-of-load conversion, telecom, networking and industrial equipment.
