NCP6360

Mini Buck Converter for

RF Power Amplifiers

The NCP6360, a PWM synchronous step−down DC−to−DC

converter, is optimized for supplying RF Power Amplifiers (PAs) used

into 3G/4G wireless systems (Mobile/ Smart Phones, Phablets,

Tablets, ...) powered by single−cell Lithium−Ion batteries. The device

is able to deliver up to 800 mA. The output voltage is monitorable

from 0.6 V to 3.4 V by an analog control pin VCON. The analog

control allows dynamically optimizing the RF Power Amplifier’s

efficiency during a communication while for example in roaming

situation with as a benefit an increased talk time. Also at light load for

optimizing the DC−to−DC converter efficiency, the NCP6360 enters

automatically in a PFM mode and operates in a slower switching

frequency corresponding to a reduced quiescent current in regards to

the PWM mode for which the device operates at a switching frequency

of 6 MHz. Synchronous rectification offers improved system

efficiency. The NCP6360 is available in a space saving, low profile

1.5 x 1.0 mm CSP−6 package.
