PCA9410/9410A 3.0 MHz, 500 mA, DC-to-DC boost converter Rev. 1 5 August 2016 Product data sheet 1. General description The PCA9410 and PCA9410A are highly efficient 3.0 MHz, 500 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 a switching frequency of 3 MHz allows using 1 H inductor or smaller. 2. Features and benefits Efficiency up to 94 % 3 % output voltage accuracy at nominal and static conditions 3 % output voltage accuracy over full current, voltage and temperature range V V , (Pass-Through Mode Operation) IN O Load disconnect Current-mode controller Soft start function for limiting inrush current with true load disconnect 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 a smaller antenna, or for greater signal strength 3.
