TPS62300DRCR

The TPS62300DRCR is a high-frequency synchronous step-down DC-to-DC Converter optimized for battery-powered portable applications. Intended for low-power applications, the TPS623xx supports up to 500mA load current and allows the use of tiny, 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 5.4V down to 0.6V, the device supports the low-voltage TMS320 DSP family, processors in smart-phones and PDAs as well as notebooks. The TPS62300 operates at 3MHz 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 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 3MHz.
