APT-BUCK belongs to power management IC and supports average power tracking (APT) of power amplifiers. APT-BUCK supports a wide range of power supply voltages and can meet system performance requirements such as accuracy, output power, and high efficiency. RM8501A meets the requirements of multi-mode 3G/4G/5G handheld systems and HPUE/PC2 at peak power output. It has fast dynamic voltage supply (DVS) performance and low overshoot/undershoot, providing output voltage with minimal ripple over a wide output voltage range. APT-BUCK power supply is usually used to provide stable voltage and current for devices, ensuring their normal operation. It can be widely used in various electronic devices, such as mobile phones, tablets, laptops, etc.
