description  
The TPS5211 is a hysteretic 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 equal the reference voltage or 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 power sequencing.  
Inhibit and undervoltage lockout assures the 12-V supply voltage and system supply voltage (5 V or 3.3 V) is  
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 TPS5211 is available in a 28-pin TSSOP PowerPAD package. It operates over  
a junction temperature range of 0°C to 125°C.
