The PCA9410 and PCA9410A are highly efficient 3.0 MHz, 300 mA, step-up DC-to-DC converters.They convert input voltages from 2.5 V to 5.25 V to a fixed output voltage of 5.0 V.

These devices are optimized for battery-powered applications. High efficiency of up to 94% enables an extended battery life in all portable designs. Step-up operation at aswitching frequency of 3 MHz allows using 1 μH inductor or smaller.

• Efficiency up to 94 %
• ±2 % 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
• Soft start function for limiting inrush current with true load disconnect
• Reverse current, overcurrent and over-temperature protection
• The PCA9410 totally disconnects input to output when disabled
• The PCA9410A connects input to output when disabled
• Wafer-Level Chip-Size Package (WLCSP) with 0.4 mm pitch; allows for the use of asmaller antenna, or for greater signal strength
