description
The TPS5300 is a hysteretic synchronous-buck controller, with two on-chip linear regulator controllers,
incorporating speed-step output voltage positioning technology. The TPS5300 provides a precise,
programmable supply voltage to a mobile processor. 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 1.30 V to 2 V in 50 mV. 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. The
TPS5300 includes high-side and low-side gate drivers rated at 2 A typical, that enable efficient operation at
higher frequencies and drive larger or multiple power MOSFETs. An adaptive dead-time circuit minimizes
dead-time losses while preventing cross-conduction of high-side and low-side switches. All three outputs power
up together as they track the same user programmable slowstart voltage. The enable external (ENABLE_EXT)
terminal allows the TPS5300 to activate external switching controllers for additional system power
requirements.
