Beschreibung

Evaluation kit EVAL-LT7170-1-AZ is a dual-phase single-output monolithic DC/DC synchronous step-down regulator with a 2.9V or 1.5V with EXTVCC to 16V input range featuring LT®7170-1. The output can supply 20A continuous load current. The Silent Switcher® regulator structure is incorporated into the LT7170-1 to minimize EMI and reduce PCB layout sensitivity. It also integrates digital power system management functionality, allowing for programmability and telemetry with a PMBus/I2C compliant serial interface. Refer to the LT7170-1 data sheet for more detailed information.

Eigenschaften

  • Silent Switcher® architecture: enables a compact, efficient, low EMI solution
  • PMBus/I2C serial interface○ Telemetry read back includes VOUT, IOUT, VIN, die temperature, and faults○ Programmable voltage, current limit, sequencing, soft start and stop, undervoltage and overvoltage, phase, frequency (up to 4 MHz), and loop compensation○ Integrated three times programmable NVM
  • Key parameters selectable by resistor
  • VOUT set point range: 0.4 V to 5.5 V
  • VOUT accuracy: ±0.25%, 0.6 V ≤ VOUT ≤ 1.375 V
  • Differential remote VOUT sense
  • Fast transient response
  • Wide VIN supply range: down to 2.9 V or 1.5 V with EXTVCC
  • Programmable and synchronizable: 400 kHz to 4 MHz
  • 24-lead (3.5 mm × 4 mm) LQFN package
