NCP6335FFCT2G

The NCP6335FFCT2G from On Semiconductor is a synchronous buck converter designed for portable applications. It can deliver up to 4.0 A with a programmable output voltage ranging from 0.6 V to 1.4 V in 6.25 mV steps. The device supports an input voltage range of 2.3 V to 5.5 V, making it suitable for battery-powered devices or 5 V rail applications.

This converter operates at a 3 MHz switching frequency, enabling the use of small external components. It features automatic PWM/PFM transitions for improved efficiency and a low quiescent current of 35 μA. The NCP6335FFCT2G includes an I2C control interface with interrupt and dynamic voltage scaling support, along with enable pins and power good/fail signaling.

Designed for space-saving, the NCP6335FFCT2G is housed in a compact 2.0 x 1.6 mm CSP-20 package. Its transient load helper capability allows it to share the same output rail with another DC-to-DC converter. Typical applications include smartphones and webtablets.

Key electrical specifications include a 2.3 V to 5.5 V input voltage range, a 0.6 V to 1.4 V programmable output voltage, and a maximum output current of 4 A. The switching frequency is 3 MHz, and it incorporates synchronous rectification. The operating temperature range is -40°C to 85°C.
