Description

The TPS62020 is a high efficiency synchronous step-down dc-dc converter optimized for battery pow- ered portable applications. This device is ideal for portable applications powered by a single Li-Ion battery cell or by 3-cell NiMH/NiCd batteries. With an output voltage range from 6.0 V down to 0.7 V, the TPS62020 supports low voltage DSPs and processors in PDAs, pocket PCs, as well as notebooks and subnotebook computers. The TPS62020operates at a fixed switching frequency of 1.25 MHz and enters the power save mode operation at light load currentsto 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  pin high. The difference between the TPS6202x and the TPS62021 is the logic level of the MODE pin. The TPS62021 has an active-low MODE pin. The TPS62020 supports up to 600-mA load current.
