AtionalSemiconductor company introduced LM2678 chip is a reverse regulation switched capacitor type inverter, can produce low-noise reverse bias to control the power output of GaAs PA in cell phones. With the MSOP-8 small package, the LM2678 sensorless device produces ± 1mV output ripple in less than 1ms startup time from
