The LT7175/LT7175-1 are monolithic DC/DC synchronous step-down regulators that deliver up to 24A of continuous output current. The LT7175-1 option has two switching phases that are connected to two inductors to drive a single-regulated output supply. The quick, clean, low-overshoot switching edges deliver high efficiency while minimizing electromagnetic interference (EMI) emissions. The I2C-based PMBus 1.3- compliant serial interface enables control of device functions while providing telemetry information for system monitoring. The LT7175/LT7175-1 are supported by the LTpowerPlay® graphical user interface (GUI) tool.
The controlled on-time valley current-mode control, with a 25ns typical minimum on-time, enables high switching frequency (fSW) at low output voltage (VOUT) with excellent transient response in a small overall solution size.
VOUT, fSW, and phase are selectable using external configuration resistors. Settings can also be set through the PMBus interface or stored in on-chip, three times programmable nonvolatile memory (NVM).
