  • Page 20: Application Interface Specification

    Application Interface Specification Power Supply The power supply pins of SIM5215&SIM5216 include six VBAT pins. VBAT directly supplies the power to RF PA and baseband system. For the VBAT, the ripple due to GSM/GPRS emission burst (every 4.615ms） may cause voltage drop, and the current consumption rises typically to peak of 2A. So the power supply must be able to provide sufficient current up to more than 2A.

  • Page 21: Power Supply Pin

    VBAT pins as close as possible. Also User should minimize the PCB trace impedance from the power supply to the VBAT pins through widening the trace to 80 mil or more on the board. The following figure is the recommended circuit. SIM5215&SIM5216_Hardware Design_V2.02 2012-08-31...

  • Page 22: Figure 9: Vbat Input Application Circuit

    If there is a big difference between the input voltage and the desired output (VBAT), a switching converter power will be preferable because of its better efficiency, especially at the high current situation. The following figure is the reference circuit. Note that DCDC may deprave RF performance because of ripple current intrinsically. SIM5215&SIM5216_Hardware Design_V2.02 2012-08-31...
