Part details & applications

The LT7184S is a dual-output monolithic PolyPhase DC/DC synchronous step-down regulator that delivers up to 7A of continuous current from both channels simultaneously and supports loads from -8A to +9A in either channel. The LT7184S features secondgeneration Silent Switcher^® architecture with integrated V_IN bypass capacitors for fast, clean, lowovershoot switching edges to deliver high efficiency at high switching frequencies and minimize Electromagnetic interference (EMI) emissions. The I²Cbased PMBus 1.3-compliant serial interface enables control of device functions and provides telemetry information for system monitoring. The LT7184S is supported by the LTpowerPlay^® graphical user interface tool. The output voltage, frequency, phase, and device address can be configured using resistors for operation without programming. Settings can also be written via the serial interface and/or stored in EEPROM. The controlled on-time valley current mode control architecture with 25ns (typical) minimum on-time enables high switching frequency at low output voltage with excellent transient response in a small overall solution size.
