3.0 MHz, 500 mA, DC-to-DC boost converter

Rev. 1.1 — 5 August 2016

Product data sheet

1. General description

The PCA9411 and PCA9411A 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

5.25 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_INV_O, (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 PCA9411 totally disconnects input to output when disabled

 The PCA9411A 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

 I_OUT 400 mA at V_IN= 2.5 V

 I_OUT 480 mA at V_IN= 3.6 V

 I_OUT 640 mA at V_IN= 4.8 V

 I_OUT 700 mA at V_IN= 5.0 V

3. Applications

 Smartphones

 NFC terminals
