Analog Devices Inc. LT7182S Dual-Output Step-Down Regulator is a dual-output monolithic PolyPhase DC/DC synchronous step-down regulator. It can simultaneously deliver up to 6A of continuous current from both channels and support loads up to 8A from either channel. The LT7182S 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. The Analog Devices LT7182S 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 may also be written via the serial interface and/or stored in EEPROM. The controlled on-time valley current mode control architecture with 20ns (typical) minimum on-time enables high switching frequency at low output voltage with excellent transient response in a small overall solution size.
