MOBILE CPU POWER SUPPLY CONTROLLER

The TPS5300 is a hysteretic synchronous-buck controller, with two on-chip linear Regulator controllers, incorporating dynamic output voltage positioning technology. The TPS5300 provides a precise, programmable supply voltage to a mobile processor or other processor power applications. A ripple Regulator provides the core voltage, while two linear Regulator drivers regulate external NPN Power Transistors for the I/O and CLK voltages. A 5-bit voltage identification (VID) DAC allows programming for the ripple Regulator voltage to values between 0.925 V to 1.275 V in 25-mV steps and 1.3 V to 2 V in 50-mV steps. Other voltage ranges and steps CAN be easily set. The fast transient response time and active voltage DROOP positioning reduce the number of output capacitors required to keep the output voltage within tight dynamic voltage regulation limits. The power saving mode (PSM) allows the user to select a single operating ramp or allows the controller to automatically Switch to lower frequencies at low loads. The high-gain Current Sense differential Amplifier allows the use of small-value sense resistors that minimize conduction losses. By Texas Instruments
