Electronics SAT1000 Point-of-Load Digital Switching Regulator 4.5Vdc - 12Vdc Input, 12A Output Current Features Input Range 4.5V to 12V Configurable Output Voltages: 0.6V to 5.5V Up to 12A Output Current Integrated Input/Output Capacitors Optimized fast transient response Power Good Enable Synchronization Input Internal Soft Start Efficiencies up to 97% Factory Configurable parameters o Voltage Margining o Current Limit o Under-Voltage Lockout 29-Pin SIP Description The SAT1000 is a non-isolated PowerCell module designed for high reliability, military & Commercial point of load applications. Fully integrated, the SAT1000 includes controller, inductor, and input capacitors integrated in a single package. The SAT1000 operates from an input voltage of +4.5V to +12V providing step down power conversion to any output voltage from 0.6V to 5.5V. This unit has many factory configurable features such as output voltage margining, current limit, under voltage lockout and transient response. Factory configuration of critical parameters results in a part that is tuned to your specific application requirements. Careful design and layout ensure excellent stability, transient response, and low noise operation. Packaged in compact FR4 SIP package, the SAT1000 is designed for controlled environment, distributed power applications and operates over a temperature range of -40 oC to +105 oC.
