DESCRIPTION  
The TPS55065 is a switch-mode regulator with integrated switches for voltage-mode control. With the aid of  
external components (LC combination), the device regulates the output to 5 V ±3% for a wide input-voltage  
range.  
The TPS55065 offers a reset function to detect and indicate when the 5-V output rail is outside of the specified  
tolerance. This reset delay is programmable using an external timing capacitor on the REST terminal.  
Additionally, an alarm (AOUT) feature is activated when the input supply rail Vdriver is below a prescaled specified  
value (set by the AIN terminal).  
The TPS55065 has a frequency-modulation scheme to minimize EMI. The clock modulator permits a modulation  
of the switching frequency to reduce interference energy in the frequency band.  
The 5Vg output is a switched 5-V regulated output with internal current limiting to prevent RESET from being  
asserted when powering a capacitive load on the supply line. This function is controlled by the 5Vg_ENABLE  
terminal. If there is a short to ground on this output (5Vg output), the output self-protects by operating in a  
chopping mode. This does, however, increase the output ripple voltage on VOUT during this fault condition.
