LTM4626 20VIN, 12A Step-Down DC/DC µModule Regulator
FEATURES DESCRIPTION
n
Complete Solution in <1cm2 (Single-Sided PCB) or
The LTM®4626 is a complete 12A step-down switching
0.5cm2 (Dual-Sided PCB)
mode µModule (micromodule) regulator in a tiny 6.25mm n
6.25mm × 6.25mm × 3.87mm BGA Package
× 6.25mm × 3.87mm BGA package. Included in the pack- n Wide Input Voltage Range: 3.1V to 20V age are the switching controller, power FETs, inductor and n 0.6V to 5.5V Output Voltage support components. Operating over an input voltage n 12A DC Output Current range of 3.1V to 20V, the LTM4626 supports an output n ±1.5% Maximum Total DC Output Voltage Error voltage range of 0.6V to 5.5V, set by a single external Over Line, Load and Temperature resistor. Its high efficiency design delivers up to 12A n Differential Remote Sensing Amp continuous output current. Only bulk input and output n Current Mode Control, Fast Transient Response capacitors are needed. The LTM4626 product video is n External Frequency Synchronization available on website. n Multiphase Parallel Current Sharing with The LTM4626 supports selectable discontinuous mode Multiple LTM4626s operation and output voltage tracking for supply rail n Output Voltage Tracking sequencing. Its high switching frequency and current n Selectable Discontinuous Mode mode control enable a very fast transient response to n Power Good Indicator line and load changes without sacrificing stability. n Overvoltage, Overcurrent and Overtemperature Protection Fault protection features include overvoltage, overcurrent and overtemperature protection.
APPLICATIONS
The LTM4626 is available with SnPb or RoHS compliant n terminal finish. Telecom, Datacom, Networking and Industrial Equipment All registered trademarks and trademarks are the property of their respective owners. n Medical Diagnostic Equipment
