TPS6102x 96% Efficient Synchronous Boost Features 3 DescriptionThe TPS6102x family 96% Efficient Synchronous Boost Converter supply solution for• Output Voltage Remains Regulated When Input cell, two-cell,or three-cellVoltage Exceeds Nominal Output Voltage one-cell Li-Ionor Device Quiescent Current:25 µA (Typ) can go as high as
alkaline battery, and dischargeit downto 0.9V. The• Input Voltage Range: 0.9Vto 6.5V device can also be used for generating5Vat 500• Fixed and Adjustable Output Voltage Options Up mA froma 3.3-V railora Li-Ion battery. The boostto 5.5V converteris based ona fixed-frequency, pulse width Power Save Modefor Improved Efficiencyat Low modulation (PWM) controller usinga synchronous
Output Power rectifierto obtain maximum efficiency. At low load
currents the converter enters the power save modeto• Low Battery Comparator maintaina high efficiency overa wide-load current• Low EMI-Converter (Integrated Anti-ringing range. The Power Save mode can be disabled,Switch) forcing the converterto operateata fixed switching Load Disconnect During Shutdown frequency. The maximum peak currentin the boost
switchis limitedtoa valueof 800 mA, 1500 mA,or• Overtemperature Protection 1800 mA depending on the versionof the device.• Small 3-mm× 3-mm VSON-10 Package
The TPS6102x devices keep the output voltage
regulated even when the input voltage exceeds the
2 Applications nominal output voltage. The output voltage can be• All One-Cell, Two-Cell, and Three-Cell Alkaline, programmed by an external resistor divider, orisNiCdor NiMH,or One-Cell Li-Ionor Li-Polymer fixed internally on the chip. The converter can beBattery-Powered Products disabledto minimize battery drain. During shutdown,
the loadis completely disconnected from the battery.• Portable Audio Players low-EMI modeis implementedto reduce ringing• PDAs and,in effect, lower radiated electromagnetic energy• Cellular Phones when the converter enters the discontinuous Personal Medical Products conduction mode. The deviceis packagedina 10-pin
VSON PowerPAD™ package measuring3 mmx3• Camera White LED Flash Lights mm (DRC).
