GLOBALFOUNDRIES 0.13um 3.3V-1.2V 200mA Synchronous Buck DC-DC

Overview

The IP is a high efficiency, low ripple, current mode buck switching regulator with internal synchronous MOS switches, eliminating the need for external Schottky diode.

Key Features

  • Process: GLOBALFOUNDRIES 0.13μm 3.3V/1.2V 1P6/7/8M Logic Process
  • Efficiency: 92% when IOUT=200mA (AVDD/PVDD=3.3V, considering the 100mΩ parasitic resistance of PVDD and PGND respectively, 300mΩ parasitic resistance of AVDD and AGND respectively and 100mΩ ESR of external inductor; if the parasitic resistance because of bonding, lead frame, PCB trace and ESR of external inductor is smaller, the efficiency will be higher.)
  • Input Voltage: 2.7~3.6V
  • Output Voltage: 1.2V±5%
  • Max Output Current: 200mA
  • Oscillation Frequency: ~1MHz
  • Over Current Protected: ~470mA
  • Standby Current: <250μA when E=AVDD/PVDD,IOUT=0A
  • Shut Down Current: <8μA when E=0V
  • Soft Start-up Time: max 0.8ms from active E to VOUT=1.2V
  • External inductor: 4.7μH with DCR lower than 100mΩ
  • External Output Capacitor: >4.7μF with ESR from 0 to 50mΩ
