TPS62200DBVT, Преобразователь постоянного тока понижающий синхронный подстраиваемый 0.3А

Описание TPS62200DBVT The TPS62200DBVT is a high-efficiency synchronous Step-down Converter ideally suited for portable systems powered by 1-cell Li-ion or 3-cell NiMH/NiCd batteries. The device is also suitable to operate from a standard 3.3 or 5V voltage rail. With an output voltage range of 6V down to 0.7V and up to 300mA output current, the device is ideal to power low voltage DSPs and processors used in PDAs, pocket PCs and smart phones. Under nominal load current, the device operates with a fixed switching frequency of typically 1MHz. At light load currents, the part enters the power save mode operation, the switching frequency is reduced and the quiescent current is typically only 15µA, therefore, it achieves the highest efficiency over the entire load current range. The TPS6220x needs only three small external components. An advanced fast response voltage mode control scheme achieves superior line and load regulation with small ceramic input and output capacitors. • High efficiency over wide load current range • Due to power save mode • Soft-start function • 100% Duty cycle low-dropout operation • Dynamic output voltage positioning • Up to 95% High efficiency • 15µA Typical quiescent current • Green product and no Sb/Br Тип преобразователяstep-downДиапазон входных напряжений, В2.5…6Диапазон выходных напряжений, В0.7…6Максимальный выходной ток, А0.3Рабочая частота, кГц1000Температурный диапазон, C-40…85Тип корпусаsot23-5Вес, г0.08
