Introduction

Reference Figure 2, a block diagram of the TPS2410EVM and TPS2411EVM.

• The 5-V supply is used to power status LEDs. It is jumper selected to power VDD on the TPS2410s

and the glitch circuit if the control voltage is less than 3.0 V.

• The status outputs turn on LEDs to give a visual condition of the system Fault, power good and gate

status are displayed.

• The Glitch maker, discussed in the Test Methods Section applies a 1-Ω load to the input supply for

100 μs. This disruption allows the user to scope test points and observe system recovery.

• The RSET resistor is used to program the turn-off point of the TPS2411.

• The Filter compensates for system noise.

• The UV and OV circuits set permissible limits for input operating voltage.
