Description
General part information
TPS65051-Q1 Series
The TPS65051-Q1 device is an integrated power-management IC for applications powered by one Li-Ion or Li-Polymer cell, which requires multiple power rails. The TPS65051-Q1 device provides two efficient, 2.25-MHz step-down converters targeted at providing the core voltage and I/O voltage in a processor-based system. Both step-down converters enter a low-power mode at light load for maximum efficiency across the widest possible range of load currents.
For low-noise applications, the user can force the devices into fixed-frequency PWM mode by pulling the MODE pin high. Operating in the shutdown mode reduces the current consumption to less than 1 μA. The devices allow the use of small inductors and capacitors to achieve a small solution size. The TPS65051-Q1 device provides an output current of up to 1 A (DCDC1) and 0.6 A (DCDC2). The TPS65051-Q1 device also integrates two 400-mA LDO and two 200-mA LDO voltage regulators, which one can turn on or off using separate enable pins on each LDO. Each LDO operates with an input voltage range between 1.5 V and 6.5 V, allowing the supply to be from one of the step-down converters or directly from the main battery.
The LDO voltage of the TPS65051-Q1 device is adjustable using external resistor dividers.
