The OM71122 is a power management IC that supports average power tracking (APT) for power amplifiers. The buck converter mechanism allows for a wide range of supply voltages and maintains system performance such as accuracy, output power and high efficiency. This ensures that OM71122 meets peak power requirements for Pas in a multimode 3G/4G/5G handheld system and HPUE/PC2 operation. The buck converter owns a fast Dynamic-Voltage-Supply (DVS) performance and low over/under shoot which supplies an output voltage with minimal ripple over a wide output voltage range.
