Pin Functions

PIN TYPE DESCRIPTION
NO. NAME
1 dVdt Analog I/O A capacitor from this pin to GND sets the output turn on slew rate. Leave this pin floating for the fastest turn on slew rate. (See Switching Characteristics).
2 EN/UVLO Analog input Active high enable for the TPS2595x0, TPS2595x1, TPS2595x5 variants. A resistor divider can be used to adjust the undervoltage lockout threshold. Do not leave floating.
EN/OVLO Active low enable for the TPS2595x3 variants. A resistor divider can be used to adjust the overvoltage lockout threshold. Do not leave floating.
3,4 IN Power Power input
5 OUT Power Power output
6 FLT Digital output TPS2595x0, TPS2595x1, TPS2595x3: Fault event indicator which is pulled low when a fault is detected. It is an open drain output that requires an external pull up resistance.
QOD TPS2595x5: Quick Output Discharge Pin, when tied to OUT directly or through external resistor.
7 ILM Analog I/O This is a dual function pin used to limit and monitor the output current. An external resistor from this pin to GND sets the output current limit. The pin voltage can also be used to monitor the output load current. Do not leave floating.
8 GND Ground Ground
PAD GND Thermal/Ground The exposed pad is used primarily for heat dissipation and must be connected to GND.
