for
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
frequency and enters the power-save mode operation
at light load currents to maintain high efficiency over
the entire load current range. For low noise appli-
cations, 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
μ
A.
The TPS623xx is available in a 10-pin leadless
package (3 x 3 mm QFN) and an 8-pin chip-scale
package (CSP).
