description  
The TPS5210 is a synchronous-buck regulator controller which provides an accurate, programmable supply  
voltage to microprocessors. An internal 5-bit DAC is used to program the reference voltage to within a range  
of 1.3 V to 3.5 V. The output voltage can be set to be equal to the reference voltage or to some multiple of the  
reference voltage. A hysteretic controller with user-selectable hysteresis and programmable droop  
compensation is used to dramatically reduce overshoot and undershoot caused by load transients. Propagation  
delay from the comparator inputs to the output drivers is less than 250 ns. Overcurrent shutdown and crossover  
protection for the output drivers combine to eliminate destructive faults in the output FETs. The softstart current  
source is proportional to the reference voltage, thereby eliminating variation of the softstart timing when  
changes are made to the output voltage. PWRGD monitors the output voltage and pulls the open-collector  
output low when the output drops 7% below the nominal output voltage. An overvoltage circuit disables the  
output drivers if the output voltage rises 15% above the nominal value. The inhibit pin can be used to control  
powersequencing. Inhibitandundervoltagelockoutassuresthe12-Vsupplyvoltageandsystemsupplyvoltage  
(5 V or 3.3 V) are within proper operating limits before the controller starts. Single-supply (12 V) operation is  
easily accomplished using a low-current divider for the required 5-V signals. The output driver circuits include  
2-A drivers with internal 8-V gate-voltage regulators. The high-side driver can be configured either as a  
ground-referenced driver or as a floating bootstrap driver. The TPS5210 is available in a 28-pin SOIC package  
and a 28-pin TSSOP PowerPAD package. It operates over a junction temperature range of 0°C to 125°C.
