AAT1299
Low Voltage 2MHz Step-Up DC/DC Converter
General Description
Features
SwitchReg
The AAT1299 is a high efficiency, synchronous,
fixed frequency, step-up converter with start-up
inrush current limit and short-circuit protection. The
input voltage ranges from 1.0V to the output voltage.
The high 2MHz switching frequency and completely
integrated control circuitry minimize the total solution
footprint area while maintaining excellent regulation,
www.DataSheet4U.croipmple, and transient response throughout the full
load range.
Light load switching frequency modulation and low
quiescent current maintain high efficiency perform-
ance for light load and sleep mode conditions.
With a 1A peak switch current limit, the AAT1299 is
capable of delivering 200mA to the load from a
1.8V input.
The AAT1299 is available in a Pb-free, space-sav-
ing 2.0x2.1mm 8-pin SC70JW or 2.2x2.2mm 10-
pin STDFN package, or in die form and is rated
over the -40°C to +85°C temperature range.
• 200mA Output from a 1.8V Input
• VIN Operation Range: 1.0V to VOUT
• Up to 93% Efficiency
• Low Start-Up Voltage: 1.0V Typical
• Internal Synchronous Rectifier
• Current Mode Control with Internal Feedback
and Compensation
• 2MHz Fixed Switching Frequency
• 1A Current Limit
• Maintains High Efficiency Over the Output
Current Range for Improved Battery Life
• Low 40µA No Load Bias Current
• Short-Circuit and Over-Current Protection
• Inrush Current Limit and Soft Start
• Low Shutdown Current: <1.0µA
• -40°C to +85°C Temperature Range
• 2.0x2.1mm SC70JW-8 or 2.2x2.2mm 10-pin
STDFN Package or Die
