1 / 28 page  LTM4657 1 Rev. A For more information www.analog.com TYPICAL APPLICATION FEATURES DESCRIPTION 20VIN, 8A Step-Down DC/DC µModule Regulator The LTM®4657 is a complete 8A step-down switching mode µModule (micromodule) regulator in a tiny 6.25mm × 6.25mm × 3.87mm BGA package. Included in the pack- age are the switching controller, power FETs, inductor and support components. Operating over an input voltage range of 3.1V to 20V, the LTM4657 supports an output voltage range of 0.5V to 5.5V, set by a single external resistor. Its high efficiency design delivers up to 8A con- tinuous output current. Only bulk input and output capac- itors are needed. The LTM4657 supports selectable discontinuous mode operation 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 incl0ude overvoltage, overcur- rent and overtemperature protection. The LTM4657 is available with SnPb or RoHS compliant terminal finish. 8A, 1.0V Output DC/DC µModule® Step-Down Regulator Efficiency vs Load Current for VOUT = 1V APPLICATIONS n Complete Solution in <1cm2 (Single-Sided PCB) or 0.5cm2 (Dual-Sided PCB) n 6.25mm × 6.25mm × 3.87mm BGA Package n Wide Input Voltage Range: 3.1V to 20V n 0.5V to 5.5V Output Voltage n 8A DC Output Current n ±1.5% Maximum Total DC Output Voltage Error Over Line, Load and Temperature n Differential Remote Sensing Amp n Current Mode Control, Fast Transient Response n External Frequency Synchronization n Multiphase Parallel Current Sharing with Multiple LTM4657s n Output Voltage Tracking n Selectable Discontinuous Mode n Power Good Indicator n Overvoltage, Overcurrent and Overtemperature Protection n Pin Compatible with LTM4626(12A) and LTM4638(15A) n Telecom, Datacom, Networking and Industrial Equipment n Medical Diagnostic Equipment n Data Storage Rack Units and Cards n Test and Debug Systems VIN RUN INTVCC MODE/CLKIN TRACK/SS PHMODE LTM4657 FREQ CLKOUT VOUT VOSNS+ 10µF 100µF x2 VIN 3.1V TO 20V VOUT 1.0V 8A FB PGOOD COMPa COMPb GND 60.4k VOSNS– 4657 TA01a 0.1µF OUTPUT LOAD CURRENT (A) 0 95 70 90 80 85 75 65 7 4 4657 TA01b 8 5 6 3 1 2 12VIN 5VIN 500kHz All registered trademarks and trademarks are the property of their respective owners.
