6-channel Power Mgmt IC With 2 DC/DCs, 4 LDOs, In 4x4mm QFN

The TPS6505x are integrated Power Management ICs for applications powered by one Li-Ion or Li-Polymer cell, which require multiple power rails. The TPS6505x 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 devices CAN be forced into fixed frequency PWM mode by pulling the MODE pin high. In the shutdown mode, the current consumption is reduced to less than 1 A. The devices allow the use of small inductors and capacitors to achieve a small solution size. TPS6505x provides an output current of up to 1 A on each DC/DC converter. The TPS6505x also integrate two 400-mA LDO and two 200-mA 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 1.5 V and 6.5 V allowing them to be supplied from one of the Step-down converters or directly from the main battery.
Four digital input pins are used to set the output voltage of the LDOs from a set of 16 different combinations for LDO1 to LDO4 on TPS65050 and TPS65052. In TPS65051 TPS65054 and TPS65056 the LDO voltages are adjustable using external resistor dividers.
The TPS6505x come in a small 32-pin leadless package (4 mm x 4 mm QFN) with a 0.4 mm pitch.
