HAP5001
Description
The HAP5001 is a high efficiency Buck-Boost dc-dc converter designed for use in conjunction with RF power amplifiers in multi-mode 3G/4G/5G devices with HPUE/PC2 support. The buck-boost mechanism allows HAP5001 to maintain a wide range of output voltage with minimal ripple, while still maintaining high performance such as linearity, output power and efficiency .Patented loop control technology allows HAP5001 to have excellent transient performance such as voltage ramping/line regulation/ load regulation transient.
