onsemi Voltage Regulators - DC DC Switching Regulators NCP6335DFCT1G

The NCP6335DFCT1G is a synchronous buck converter designed for portable applications powered by single-cell Li-Ion or three-cell Alkaline/NiCd/NiMH batteries. It can deliver up to 2.5 A in a stand-alone configuration with a programmable output voltage range from 0.6 V to 1.4 V in 6.25 mV steps. The device operates at a switching frequency of 3 MHz, allowing for the use of smaller external components, specifically a 470 nH inductor and two 22 µF capacitors, optimizing the footprint and solution thickness. This voltage regulator features low quiescent current of 35 µA, I2C control interface with interrupt and dynamic voltage scaling support, and includes thermal protections for enhanced reliability. The NCP6335DFCT1G is packaged in a compact 2.0 x 1.6 mm CSP-20 format, making it suitable for space-constrained applications such as smartphones and web tablets. It also supports transient load sharing with other DC-DC converters, enhancing its versatility in power management solutions.
