Output Voltages for DC/DC Converters

DESCRIPTION

–

TPS65050: Externally Adjustable

TPS65051: Externally Adjustable

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.

TPS65052: DCDC1 = Fixed at 3.3 V;

DCDC2 = 1 V / 1.3 V for Samsung

Application Processors

–

TPS65054: DCDC1 = Externally Adjustable;

DCDC2 = 1.3 V / 1.05 V for OMAP™1710

Processor

TPS65056: DCDC1 = Fixed at 3.3 V;

DCDC2 = 1 V / 1.3 V for Samsung

Application Processors

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 µA. The

devices allow the use of small inductors and

Power Save Mode at Light Load Current

180° Out-of-Phase Operation

capacitors to achieve

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.

Output Voltage Accuracy in PWM mode ±1%

Low Ripple PFM Mode

Total Typical 32-µA Quiescent Current for

Both DC/DC Converters

•

100% Duty Cycle for Lowest Dropout

Two General-Purpose 400-mA, High PSRR

LDOs

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.

Two General-Purpose 200-mA, High PSRR

LDOs

•

V_Irange for LDOs from 1.5 V to 6.5 V

Digital Voltage Selection for the LDOs

The TPS6505x come in a small 32-pin leadless

package (4 mm x 4 mm QFN) with a 0.4 mm pitch.

Available in a 4 mm x 4 mm 32-Pin QFN
