The Texas Instruments TPS62065 and TPS62067 are highly efficient synchronous step down DC-DC converters that provide up to 2.0A output current. The TI TPS62065 and TPS62067 feature an input voltage range of 3.0V to 6V, making these devices a perfect fit for power conversion from a 5V or 3.3V system supply rail. These TI step down DC-DC converters operate at 3MHz fixed frequency and enter Power Save Mode operation at light load conditions to maintain high efficiency over the entire load current range. For low noise applications, TPS62065 can be forced into fixed frequency PWM mode by pulling the MODE pin high. The TPS62067 provides an open drain power good output. These TI DC-DC converters are ideal for POL applications as well as notebooks / pocket PCs, portable media players, and DSP supply.
