APS1056 Fast Transient 600mA Step-Down Converter General Description The APS1056 SwitchReg is a member of AnalogicTech's Total Power Management IC™ (TPMIC™) product family. It is a 1.4MHz stepdown converter with an input voltage range of 2.7V to 5.5V and output voltage as low as 0.6V. It is optimized to react quickly to a load variation. The APS1056 is available in fixed voltage versions with internal feedback and a programmable version with external feedback resistors. It can deliver 600mA of load current while maintaining a low 27µA no load quiescent current. The 1.4MHz switching frequency minimizes the size of external components while keeping switching losses low.
