5 V • Power Save Mode for Improved Efficiency at Low Output Power • Low Battery Comparator • Low EMI-Converter (Integrated Anti-ringing Switch) • Load Disconnect During Shutdown • Over-Temperature Protection • Small 3-mm × 3-mm QFN-10 Package 2 Applications • All One-Cell, Two-Cell and Three-Cell Alkaline, NiCd or NiMH or Single-Cell Li Battery Powered Products • Portable Audio Players • PDAs • Cellular Phones • Personal Medical Products • Camera White LED Flash Light 3 Description The TPS6102x devices provide a power supply solution for products powered by either a one-cell, two-cell, or three-cell alkaline, NiCd or NiMH, or onecell Li-Ion or Li-polymer battery.
Output currents can go as high as 200 mA while using a single-cell alkaline, and discharge it down to 0.
9 V.
It can also be used for generating 5 V at 500 mA from a 3.
3-V rail or a Li-Ion battery.
The boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using a synchronous rectifier to obtain maximum efficiency.
At low load currents, the converter enters the Power Save Mode to maintain a high efficiency over a wide load current range.
The Power Save Mode can be disabled, forcing the converter to operate at a fixed switching frequency.
The maximum peak current in the boost switch is limited to a value of 800 mA, 1500 mA or 1800 mA depending on the device version.
The TPS6102x devices keep the output voltage regulated even when the input volt...
