DESCRIPTION
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.
