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.
