The superior properties of Li-ion batteries, such as high energy density, light weight, no memory effect, and less self-discharge, make them a very popular option in portable applications.
ICs with boost topology are needed in portable applications since the voltage fluctuation of most Li-ion batteries ranges from 4,2 V (fully charged) to 3,0 V (fully discharged), while the post-circuit input voltage is up to 12 V or more.
Portable applications, such as Bluetooth audio, quick-charge power banks and portable POS systems, employ various boost products available in the market, including discrete controllers with external MOSFETs, non-synchronous boost converters with an external diode, and limited input/output voltage ranges or features. These solutions take up more space, require more components while providing less efficiency, and compromise performance in terms of noise and reliability.
The MP3432 from Monolithic Power Systems (MPS) operates from an input voltage as low as 2,7 V, supports an operating input voltage from 0,8 V to 13 V, and an output voltage up to 16 V. Furthermore, it integrates two synchronous MOSFETs with optimised features, such as a programmable switching current limit up to 21,5 A, up to 30 W of load power from a single-cell battery, pass-through mode in pulse-skip mode (PSM) operation, various operation modes, and high power density in a QFN (3 x 4 mm) package.
This converter eliminates the need for inefficient and bulky external Schottky diodes by integrating small 6,5 mΩ and 10 mΩ RDS(ON) power MOSFETs using MPS’ latest process technology, advanced circuit design techniques and packaging technology. It achieves peak efficiency up to 97% at a 4,2 V input voltage and more than 85% in the main operating range with excellent thermal performance.
The MP3432 adopts a constant-off-time (COT) control topology, which provides fast transient response and reduces the output capacitance, which further contributes to reducing the overall solution size.
