Analog Devices LT7182S Product Info

The LT7182S is a dual-output monolithic PolyPhase DC/DC synchronous step-down regulator. It can deliver up to 6A of continuous current from both channels simultaneously and can support loads up to 8A from either channel. The LT7182S features the second generation Silent Switcher^® architecture with integrated V_IN 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 LT7182S 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.

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.
