TPS6505xx 5-channel power management IC, 2 buck converters, 3 low input voltage LDOs

TPS6505xx series devices integrate 1 Ω up to 95% efficiency power management IC for DC-DC converters: One Li-Ion or Li-Polymer battery, multiple required - TPS65053: DCDC1 = 1 A; DCDC2 = 0.6 A power supply Wire. The TPS6505xx devices provide two high-efficiency 2.25 MHz buck converters - TPS650531, TPS650532: DCDC1 = 1 A; core voltage and I/O voltage cdc2 = 1 A for processor-based systems. Two bucks - TPS65058: DCDC1 = 0.6 A; DCDC2 = 1 A Converter enters low power mode at light load, for ?TPS65053, TPS650531, TPS650532: DC-DC maximum efficiency is externally adjustable through the widest load current Range converter. For low noise applications, the device can be forced into a fixed frequency PWM? TPS65058: DCDC1 is fixed at 3.3V, DCDC2 mode, by pulling the mode pin high. The tps6505xx1 is selectable between 1.8V and 1.2V, with dynamic devices, and also integrates a 400mA LDO and two 200mA voltage regulators for the core processor to supply the mA LDO regulator. For DC-DC converters, each LDO operates from ~VIN with input voltages ranging from 1.5 V to 6.5 V, from 2.5 V to 6v, allowing them to be powered by a buck converter or directly from the main battery . ? 2.25 mhz fixed frequency operation ?
