General Description

The DA9389 is a bi-directional switched capacitor converter capable of up to 6A output current and targeting 2S or 3S battery-powered applications.

When a mobile device is connected to any USB input voltage between 4 V and 13.5 V, the DA9389 can be used in current multiplier (voltage divider) mode to half the voltage applied to the V2X pin and double the available current to the system.

It can also be configured to forward BYPASS and supply the V2X pin voltage directly to the system.

Key Features

  • Input voltage VV2X (Divide mode) 4 V to 13.5 V.
  • Input voltage VV1X (Multiply mode) 2.5 V to 6.5 V.
  • Output voltage VV1X = 0.5.
  • VV2X (Divide mode).
  • Output voltage VV2X = 2.
  • VV1X (Multiply mode).
  • 6 A Output current (Divide mode).
  • 3 A Output current (Multiply mode).
  • 4 A Output current (BYPASS mode).
  • Typical 8 µA quiescent current.
  • Watchdog timer.
  • Spread spectrum frequency modulation.
  • Autonomous soft-start.
  • ON-key with long press.
