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. The TPS5300 features undervoltage lockout, overvoltage, undervoltage, and

user-programmable overcurrent protection, and is packaged in a small 32-pin TSSOP PowerPAD package.
