GLOBALFOUNDRIES 0.11um 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. It is the blown-up version of GF13V33_DCDCBK_04_33T12V200mA.
Key Features
- Process: GLOBALFOUNDRIES 0.11μm (90% shrink from 0.13um) 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 0mΩ to 50mΩ
- External Input Capacitor: >4.7μF with low ESR
- Operating Junction Temperature: -40°C~+25°C~+125°C
