LT7182S: Dual Channel 6 A, 20 V PolyPhase Step-Down Silent Switcher 2 with Digital Power System Management

The LT7182S is a dual-output monolithic PolyPhase DC-to-DC synchronous step-down regulator. It can deliver up to 6 A of continuous current from both channels simultaneously and can support loads up to 8 A 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.

Key Features and Benefits:

• •  I2C-based PMBus serial interface and integrated EEPROM enables telemetry information and fault logging for system monitoring
• •  Achieves ultra-high regulation with ±0.25% output voltage accuracy
• •  20 ns minimum on-time enables high switching frequency at low output voltage with excellent transient response

Applications:

• •  General Purpose: FPGAs, ASICs, microprocessor point of load supplies
• •  Industrial Automation: Solid state drives, process control, burn-in boards
• •  Communications/5G: NIC/servers, data center, satellite antenna
• •  Aerospace and Defense: Avionics

The LT7182S can be evaluated with the DC2836A
