onsemi NCP6361
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.| Part No. | NCP6361 |
