AAT1123 | 1MHz 600mA Step-Down DC/DC Converter

The AAT1123 SwitchReg is a member of AnalogicTech's Total Power Management IC (TPMIC) product family. It is a 1MHz Step-down converter with an input voltage range of 2.7V to 5.5V and output as low as 0.6V. Its low supply current, small size, and high switching frequency make the AAT1123 the ideal choice for portable applications. The AAT1123 is available in either a fixed version with internal feedback or a programmable version with external feedback resistors. It CAN deliver up to 600mA of load current while maintaining a low 25A no load quiescent current. The 1MHz switching frequency minimizes the size of external components while keeping switching losses low. The AAT1123 feedback and control delivers excellent load regulation and transient response with a small output inductor and capacitor. The AAT1123 is designed to maintain high efficiency throughout the operating range and provides fast turn-on time. The AAT1123 is available in a space-saving 2.0x2.1mm SC70JW-8 package and is rated overthe -40C to +85C temperature range.
