Power Management (PMIC)

bidirectional converterbuck boost20 AVQFN

TPS61289RZPR is a 14-pin bidirectional synchronous buck/boost converter for high-current power transfer between VLOW and VHIGH rails.

Best for

  • Bidirectional battery charge and discharge power stages
  • High-current buck/boost conversion
  • Battery testing and backup power systems

Avoid if

  • The design cannot accommodate an external low-side MOSFET and high-current inductor
  • The required voltage or current exceeds the stated operating ranges

Check before use

  • VHIGH undervoltage and overvoltage limits
  • Inductor peak current and saturation rating
  • PCB switching-current loop, grounding and thermal dissipation
