NCP6343SFCCT1G Description

Short technical summary and product information.

The NCP6343SFCCT1G from ON Semiconductor is a synchronous buck converter optimized for portable applications powered by single-cell Li-Ion or three-cell Alkaline/NiCd/NiMH batteries. This device can deliver up to 3.0 A with a programmable output voltage ranging from 0.6 V to 1.4 V in 6.25 mV steps.

 

It features a 3 MHz switching frequency, which allows for the use of small external components, contributing to a compact solution. The converter supports automatic PWM/PFM transitions to improve overall solution efficiency and offers an ultra-low 0.8 µA off-mode current and low 35 µA quiescent current. An I2C control interface is included for interrupt and dynamic voltage scaling support.

 

The NCP6343SFCCT1G is housed in a space-saving, low-profile 1.99 x 1.34 mm CSP-15 package, suitable for surface mounting. It is designed for applications such as smartphones and webtablets, where power efficiency and small footprint are critical.
