technology. The TPS5300 provides  
a
precise,  
FEATURES  
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.
