The charger can either be – Adjustable or Fixed Output Voltage supplied by a USB port on pin USB or by a dc voltage – VIN Range From 2.8V to 6.3V from a wall adapter connected to pin AC. Three – Power Save Mode at Light Load Current highly efficient 2.25MHz step-down converters are targeted at providing the core voltage, memory and – Output Voltage Accuracy in PWM Mode I/O voltage in a processor based system. The ±1.5% step-down converters enter a low power mode at light – Typical 19 μA Quiescent per Converter load for maximum efficiency across the widest – 100% Duty Cycle for Lowest Dropout possible range of load currents. For low noise applications the devices can be forced into fixed • LDOs: frequency PWM using the I2C interface. The – Fixed Output Voltage step-down converters allow the use of small inductors – Dynamic Voltage Scaling on LDO2 and capacitors to achieve a small solution size. The TPS6507x also integrate two general purpose LDOs – 20 μA Quiescent Current for an output current of 200mA. These LDOs can be – 200mA Maximum Output Current used to power an SD-card interface and an – VIN Range From 1.8V to 6.3V always-on rail, but can be used for other purposes as well. Each LDO operates with an input voltage range • wLED Boost Converter: between 1.8V and 6.3V allowing them to be supplied – Internal Dimming Using I2C from one of the step-down converters or directly from – Up to 2 × 10 LEDs the main battery. An inductive boost converter with two programmable current sinks power two strings of – Up to 25mA per String With Internal Current white LEDs. Sink • I2C Interface The TPS6507x come in a 48-pin leadless package (6mm × 6mm QFN) with a 0,4mm pitch. • 10 Bit A/D Converter 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 OMAP, PowerPAD are trademarks of Texas Instruments.
