L6984A - synchronous step-down switching regulator

General Description

The L6984 is a step-down monolithic switching regulator able to deliver up to 400 mA DC.

The output voltage adjustability ranges from 0.9 V.

The fixed 3.3 V VOUT requires no external resistor divider.

Key Features

  • 400 mA DC output current.
  • 4.5 V to 36 V operating input voltage.
  • Synchronous rectification.
  • Low consumption mode or low noise mode.
  • 75 µA IQ at light load (LCM VOUT = 3.3 V).
  • 13 µA IQ-SHTDWN.
  • Adjustable fSW (250 kHz - 600 kHz).
  • Output voltage adjustable from 0.9 V.
  • No resistor divider required for 3.3 V VOUT.
  • VBIAS maximizes efficiency at light load.
  • 350 mA valley current limit.
  • Constant on-time control scheme.
  • PGOOD open collecto.
