Transcript TPS6261x 350mA, 6-MHz High efficiency step

TPS82671/x675
600mA Fully Integrated, Low Noise Step-Down Converter in MicroSIP™
• Regulated Switching Frequency: 5.5MHz
• All required external components are
integrated
• Spread Spectrum, PWM Frequency Dithering,
High PSRR and low ripple Power Save Mode
• Automatic Power Safe Mode transition or
forced PWM Mode operation
• Input voltage: 2.3V to 4.8V
• Allows < 7mm2 total solution size, thus provides
90mA/mm2
• One-Stop-Shop, reduced HW design workload and no
more questionable designs
• Supports noise sensitive applications through improved
RF spurious performance and radiated noise reduction
• Allows to choose between high efficiency over entire
load range (PSM) or regulated fixed frequency
• Supports Li-Ion batteries with extended voltage range
