description  
The TPS3510/1 is designed to minimize external components of personal-computer switching power supply  
systems. It provides protection circuits, power good indicator, fault protection output (FPO) and PSON control.  
Overvoltage protection (OVP) monitors 3.3 V, 5 V, and 12 V (12-V signal detects via V  
pin). Undervoltage  
DD  
protection (UVP) monitors 3.3 V and 5 V. When an OV or UV condition is detected, the power good output (PGO)  
is set to low and FPO is latched high. PSON from low to high resets the protection latch. UVP function is enabled  
75 ms after PSON is set low and debounced. Furthermore, there is a 2.3-ms delay (and an additional 38-ms  
debounce) at turnoff. There is no delay during turnon.  
Power good feature monitors PGI, 3.3 V and 5 V and issues a power good signal when the output is ready.  
The TPS3510/1 is characterized for operation from –40°C to 85°C.
