MC908MR32CFUE IC_AD21489WBSWZ4B02 Introduction

The low IQ of the TPS62840 enables 80% efficiency at 1-µA loads, 30% higher than comparable devices in the industry. . Longer battery life and very high light load efficiency: Lower IQ consumption provides longer IQ for very light loads (below 100µA) and systems operating primarily in standby/factory mode (no switching) battery life.

The recharger's integrated dual input selector supports multiple power sources including wireless, USB, barrel jack and solar recharging, while providing fast recharging - up to 97% efficiency at 30 W.

There are many types of BAW filters, including ladder type filter, lattice type filter, stacked crystal filter and coupled resonator filter. Only the ladder type and lattice type are briefly introduced here. The BAW filter can connect multiple resonators according to a certain topology.

The resonator used in the Ladder type (SAW is also mentioned later) includes series and parallel. A series resonator plus a parallel resonator is called a stage, and the entire ladder type filter can be composed of several stages. .
