DESCRIPTION
The TPS62203 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 at a standard voltage rail.
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. At light load currents, the part
enters the power save mode operation and the switching frequency is reduced; therefore, it achieves the highest
efficiency over the entire load current range. The TPS62203 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.
