Synchronous Step-Down DC/DC Converter Delivers up to 500mA with Pin Selectable 1.28V/1.87 Outputs

Synchronous Step-Down DC/DC Converter Delivers up to 500mA with Pin Selectable 1.28V/1.87 Outputs
Linear Technology has announced the LTC3563, a high efficiency, 2.25 MHz, synchronous buck regulator that can deliver up to 500mA of continuous output current from a 2mm x 2mm DFN package. Its output voltage is pin-selectable to either 1.28V or 1.87V, making it ideal for the latest generation of Agere cellphone baseband chipsets. Using a constant frequency and current mode architecture, the LTC3563 operates from an input voltage range of 2.5V to 5.5V, compatible with single cell Li-Ion, or multi-cell alkaline/NiCad/NiMH applications. Its 2.25MHz switching frequency enables the utilization of tiny, low cost ceramic capacitors and inductors less than 1mm in height, providing a very compact solution footprint for handheld applications.

DC motor driver IC from Allegro has typical input voltage range of 3 to 5.5V

DC motor driver IC from Allegro has typical input voltage range of 3 to 5.5V
The A3903 from Allegro MicroSystems Europe is a low-voltage bidirectional DC motor driver IC in an ultra-compact package measuring only 2 mm square and 0.55 mm high. The new device has a typical input voltage range of 3 to 5.5 V and produces an output current up to 500 mA. The output uses a full-bridge circuit incorporating source-side linear operation to produce a constant voltage across the motor coil. This regulated output minimises motor voltage changes caused by current variations and battery voltage fluctuations.
