The TPS65053-Q1 device is integrated power management IC (PMIC) for applications powered by one Li-Ion or Li-Polymer cell, which require multiple power rails. The TPS65053-Q1 device provides two highly 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 loads 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.
The TPS65053-Q1 device provides an output current of up to 1 A on the DCDC1 converter and up to 0.6 A on the DCDC2 converter. The device also integrates one 400-mA LDO and two 200-mA LDO voltage regulators, which can be turned on and off using separate enable pins on each LDO. Each LDO operates with an input voltage range from 1.5 V to 6.5 V, 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 1.3 V.
The TPS65053-Q1 device is available in a small 24-pin leadless package (4-mm × 4-mm VQFN) with a 0,5-mm pitch.
