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

Overview

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
• External Input Capacitor: >4.7μF with low ESR
