FEATURES

Up to 95% Conversion Efficiency

Typical Quiescent Current: 18 µA

Load Current: 1.2 A

PC Cards and Notebooks

xDSL Applications

Standard 5-V to 3.3-V Conversion

Operating Input Voltage Range: 2.5 V to 6.0 V

Switching Frequency: 1.25 MHz

DESCRIPTION

Adjustable and Fixed Output Voltage

The TPS6204x family of devices are high efficiency

synchronous step-down dc-dc converters optimized for

battery powered portable applications. The devices are

ideal for portable applications powered by a single Li-Ion

battery cell or by 3-cell NiMH/NiCd batteries. With an

output voltage range from 6.0 V down to 0.7 V, the devices

support low voltage DSPs and processors in PDAs,

pocket PCs, as well as notebooks and subnotebook

computers. The TPS6204x operates at a fixed switching

frequency of 1.25 MHz and enters the power save mode

operation at light load currents to maintain high efficiency

over the entire load current range. For low noise

applications, the devices can be forced into fixed

frequency PWM mode by pulling the MODE pin high. The

TPS6204x supports up to 1.2-A load current.
