B5973D - 2A step down switching regulator

General Description

The B5973D is a step down monolithic power switching regulator with a minimum switch current limit of 2.25 A so it is able to deliver up to 2 A DC current to the load depending on the application conditions.

The output voltage can be set from 1.235 V to 35 V.

Key Features

  • Qualified following the AEC-Q100 requirements (temperature Grade 1), see PPAP for more details.
  • 2 A DC output current.
  • Operating input voltage from 4 V to 36 V.
  • 3.3 V / (± 2 %) reference voltage.
  • Output voltage adjustable from 1.235 V to 35 V.
  • Low dropout operation: 100 % duty cycle.
  • 250 kHz internally fixed frequency.
  • Voltage feedforward.
  • Zero load current operation.
  • Internal current limiting.
  • Inhibit for zero current consumption.
  • Sy.
