NXP Semiconductors PCA9410 & PCA9410A DC-to-DC Boost Converters

NXP Semiconductors PCA9410 and PCA9410A DC-to-DC Boost Converters are highly efficient 3.0MHz, 500mA, step-up converters that convert input voltages from 2.5V to 5.25V to a fixed output voltage of 5.0V. This conversion makes the NXP PCA9410 and PCA9410A DC-DC Converters optimized for battery-powered applications. A 94% high efficiency enables an extended battery life for portable designs. Step-up operation at a 3MHz switching frequency allows for using a 1µH inductor or smaller.

Features

  • Efficiency up to 94%
  • 3% output voltage accuracy at nominal and static conditions
  • 3% output voltage accuracy over full current, voltage, and temperature range
  • VIN ≥ VO (Pass-Through Mode Operation)
  • Load disconnect
  • Current-mode controller
  • Reverse current, overcurrent, and over-temperature protection
  • Soft start function for limiting inrush current with true load disconnect
  • PCA9410 (Disconnect Mode) disconnects the input to output when disabled
  • PCA9410A (Pass-Through Mode) connects the input to output when disabled
  • Wafer-Level Chip-Size Package (WLCSP) with 0.4mm pitch; allows for the use of a smaller antenna or greater signal strength

Applications

  • Smartphones
  • NFC terminals
