Product Overview

The TPS55386PWP is a dual output non-synchronous Buck Converter capable of supporting 3A output applications that operate from a 4.5 to 28V input supply voltage and require output voltages between 0.8V and 90% of the input voltage. With an internally-determined operating frequency and soft start time, it provides many features with a minimum of external components. The outputs of the two error amplifiers are accessible allowing user optimization of the feedback loop under a wide range of output filter characteristics. Channel 1 overcurrent protection is set at 4.5A, while channel 2 overcurrent protection level is selected by connecting a pin to ground, to BP or left floating. The setting levels are used to allow for scaling of external components for applications that do not need the full load capability of both outputs. The outputs may be enabled independently or configured to allow either ratiometric or sequential startup sequencing.
  • PWM outputs 180° out-of-phase
  • Ratiometric or sequential startup modes
  • Configurable as dual output or two-channel single output multiphase for 6A capability
  • Current mode control with external compensation
  • Pulse-by-pulse overcurrent protection
  • Thermal shutdown protection at 148°C
  • 3 Selectable levels of overcurrent protection
  • 85Ω Internal high-side MOSFETs
  • Green product and no Sb/Br
