† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTE 1: All voltages are with respect to the device GND terminal.

The TPS5510 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 a PSON control. OVP (Over Voltage Protection) monitors 5 V, 3.3 V, and 12 V (12 V OV detects via VCC terminal). UVP (Under Voltage Protection) monitors 5 V and 3.3 V. When an OV or UV condition of TPS5510 is detected, the PGO (power good output) is asserted low and FPO is latched high. PSON from low to high resets the protection latch. UVP function will be enabled 75 ms after PSON is set low and debounced.

Power good feature of TPS5510 monitors PGI, 5 V and 3.3 V and issues a power good signal when they are ready.

The TPS5510 is characterised for operation from TJ = 40°C to 125°C junction temperature.
