FEATURES
DESCRIPTION
The
TPS623xx
synchronous step-down dc-dc converter optimized for
battery-powered portable applications. Intended for
low-power applications, the TPS623xx supports up to
500-mA load current and allows the use of tiny, low
cost chip inductor and capacitors.

The device is ideal for mobile phones and similar
portable applications powered by a single-cell Li-Ion
battery or by 3-cell NiMH/NiCd batteries. With an
output voltage range from 5.4 V down to 0.6 V, the
device supports the low-voltage TMS320 DSP
family, processors in smart-phones, PDAs as well as
notebooks, and handheld computers.
The TPS62300 operates at 3-MHz fixed switching

applications, the device can be forced into fixed
frequency PWM mode by pulling the MODE/SYNC
pin high. The device can also be synchronized to an
external clock signal in the range of 3 MHz. In the
shutdown mode, the current consumption is reduced
to less than 1
