NCP6361 Buck Converter with Bypass Mode for RF Power Amplifiers The NCP6361, a PWM synchronous step−down DC−to−DC converter, is optimized for supplying RF Power Amplifiers (PAs) used in 3G/4G wireless systems (Mobile / Smart Phones, Tablets,…) powered by single−cell Lithium−Ion batteries. The device is able to deliver up to 2 A current in bypass mode and 800 mA in buck mode. The output voltage is monitorable from 0.4 V to 3.5 V by an analog control pin VCON. The analog control allows dynamically optimizing the RF Power Amplifier’s efficiency through the monitoring of the PA output power. With an improved overall system efficiency the communication time and phone autonomy can be consequently increased.
