Diodes has announced a family of low-power dc-dc buck converters that can deliver 2A from between 3.8V and 32V. Output voltages between 0.8 and Vin are possible. Efficiency can be 88% at 5mA out, with quiescent as low as 22µA. The devices are: AP63200: 500kHz, PWM/PFM, variable out, can operate as LDO (100% duty) AP63201: ...
