LT LTM4632IV#PBF

非隔离 PoL 模块3.6V15V0.6 ~ 2.5V3A，3A

Overview

The LTM®4632 is an ultrathin triple output step-down µModule® (power module) regulator to provide complete power solution for DDR-QDR4 SRAM. Operating from a 3.6V to 15V input voltage, the LTM4632IV#PBF 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 LTM4632IV#PBF 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 LTM4632IV#PBF 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 LTM4632IV#PBF is available with SnPb (BGA) or RoHS compliant terminal finish• Complete DDR-QDR4 SRAM Power Solution Including VDDQ, VTT, VTTR (or VREF)• Solution in 0.5cm2 (Dual-Sided PCB)• Wide Input Voltage Range: 3.6V to 15V• 3.3V Input Compatible with VIN Tied to INTVCC• 0.6V to 2.5V Output Voltage Range• Dual ±3A DC Output Current with Sink and Source Capability• ±1.5%, ±10mA Buffered VTTR = VDDQ/2 Output• 3A VDDQ + 3A VTT or Dual Phase Single 6A VTT• ±1.5% Maximum Total Output Voltage Regulation Error Over Load, Line and Temperature• Current Mode Control, Fast Transient Response• External Frequency Synchronization• Multiphase Parallelable with Current Sharing• Selectable Burst Mode® Operation• Overvoltage Input and Overtemperature Protection• Power Good Indicator• Ultrathin 6.25mm × 6.25mm × 1.82mm LGA and 6.25mm × 6.25mm × 2.42mm BGA Packages• DDR Memory Power Supply• General Purpose Point-of-Load Conversion• Telecom, Networking and Industrial Equipment
