Description

The TPS623xx device is a high-frequency 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 frequency and enters the power-save mode operation at light load currents to maintain high efficiency over the entire load current range.
