TPS65053RGET Datasheet

PMIC Solutions


The TPS65053RGET are integrated Power Management ICs for applications powered by one Li-Ion or Li-Polymer cell, which require multiple power rails. The TPS65053x provide two highly efficient, 2.25MHz 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 devices can be forced into fixed frequency PWM mode by pulling the MODE pin high. Both converters allow the use of small inductors and capacitors to achieve a small solution size.TPS65053 provides an output current of up to 1A on the DCDC1 converter and up to 0.6A on the DCDC2 converter. TPS650531 and TPS650532 provide up to 1A on both DCDC1 and DCDC2. The TPS65053x also integrate one 400mA LDO and two 200mA LDO voltage regulators, which can be turned on/off using separate enable pins on each LDO. Each LDO operates with an input voltage range between 1.5V and 6.5V allowing them to be supplied from one of the step-down converters or directly from the main battery. LDO1 and LDO2 are externally adjustable while LDO3 has a fixed output voltage of 1.3V on TPS65053, 1.2V on TPS650531 and 1.5V on TPS650532.
