ACT5102

23 V, Compact, High-Efficiency, Wide Input Range Buck-Boost Converter with Integrated MOSFETS

Qorvo's ACT5102 is a buck-boost converter with 4 integrated MOSFETs. It offers a high efficiency, low component count, compact solution with a wide input voltage range for 4 to 23 V applications.

An advanced switch control algorithm allows the buck-boost converter to maintain output voltage regulation with input voltages that are above, below or equal to the output voltage. The system can be monitored and configured by I2C interface as well.

ACT5101 and ACT5102 are identical products except for the following differences:

  • ACT5101 has internal voltage feedback while ACT5102 has external voltage feedback.
  • ACT5101's output voltage is set by internal registers while ACT5102's output voltage is set by an external resistor divider.
  • ACT5101 has ADC functionality while AC5102 does not.
