LT7182SRV#PBF

LT7182S is a dual-output monolithic polyphase DC/DC synchronous step-down regulator that delivers upto 6A of continuous current from both channels simultaneously and supports loads upto 8A from either channel. It features the second generation Silent Switcher® architecture with integrated VIN bypass capacitors for fast, clean, low-overshoot switching edges delivering high efficiency at high switching frequencies while minimizing EMI emissions. The I²C-based PMBus 1.3 compliant serial interface enables control of device functions and provides telemetry information for system monitoring. It is supported by the LTpowerPlay® graphical user interface tool. Output voltage, frequency, phase, and device address can be configured using resistors for operation without programming. Settings may also be written via the serial interface and/or stored in EEPROM. It is used in application such as communications, storage, and industrial systems, data centre and solid state drive power supplies etc.
