DESCRIPTION
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.
