PCA9410A Datasheet | NXP Semiconductors

description The PCA9410 and PCA9410A are highly efficient 3.0 MHz, 500 m A, 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 - VINVO, (Pass-Through Mode Operation) - 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. Applications - Smartphones - NFC terminals 4. Ordering information Table 1.
