User-Supplied Equipment

Required Equipment

1. Bench Power Supply for VIN – 10V/30V and 0.5A/6A, as needed for the intended application. For testing over-voltage protection and withstand voltage, a 28V adjustable bench power supply is preferred.
2. Digital Multimeter – one or more, used to measure input/output voltages and currents.

Optional Equipment

1. Bench Power Supply for VIO – 1.5V to 5V, low current. Needed for shutdown mode (̅E̅̅N̅ = VIO = High) and power good monitoring (A̅̅C̅̅O̅̅K̅ pull-up voltage).
2. Oscilloscope – for dynamic testing of voltages (and currents with a current probe, if available).
3. Load – either an eLoad, power resistors, or an actual system load.
4. Additional Digital Multimeters

Quick Start Procedures

1. Set Jumpers to default: ̅E̅̅N̅ = GND

2. Connect one pair of XT30-to-Banana power cables to the XT30 connector at VIN and GND (left edge of EVAL Kit).

3. Before connecting the EVAL Kit to the VIN bench supply, turn on the supply and adjust the voltage as close to 0V as possible. Then turn off the supply. While off, connect the banana ends of the XT30-to-Banana power cables to the VIN bench supply.

4. Turn on the VIN bench supply and very slowly ramp its voltage to an appropriate voltage, such as 5V.
   While ramping VIN slowly, use the bench supply’s output current indication (or a digital multimeter) to monitor the VIN current. If the current becomes high, reduce the VIN voltage quickly to prevent damage.
   Then inspect the setup for any wiring errors.

5. With valid VIN voltage such as 5V, use a digital multimeter to check the output voltage between the KVOUT and GND terminals on the EVAL Kit. It should be the same as the input voltage.

6. Use a digital multimeter to check the no-load supply current at VIN. Consult the KTS1693 datasheet for the expected current range at the VIN voltage condition in use. For conditions of VIN = 5V, ̅E̅̅N̅ = GND, and no-load, it should be close to 160A.

Additional Test Procedures

1. Logic Pins Testing:
   • Before connecting the EVAL Kit to the VIO bench supply, turn on the supply and adjust the voltage as close to 0V as possible. Then turn off the supply. While off, connect the VIO bench supply to VIO and GND terminals on the EVAL Kit (with user-supplied banana-to-clip leads).
   • Turn on the VIO bench supply and very slowly ramp its voltage to an appropriate voltage, such as 1.8, 3.3, or 5V. While ramping VIO slowly, use the bench supply’s output current indication (or a digital multimeter) to monitor the VIO current. If the current becomes high, reduce the VIO voltage quickly to prevent damage. Then inspect the setup for any wiring errors.
   • With valid VIO at 3V and VIN voltage at 5V, check the ̅E̅̅N̅ and A̅̅C̅̅O̅̅K̅ functionality.
   • Check the shutdown supply current at VIN with ̅E̅̅N̅ = VIO. The shutdown supply current should be around 1μA only. A̅̅C̅̅O̅̅K̅ Power Good flag pin voltage should be close to VIO = 3V.
   • With ̅E̅̅N̅ = GND, check the A̅̅C̅̅O̅̅K̅ Power Good output pulls low to GND when VIN > 2.8V (UVLO) and VIN < 5.77V (OVLO).
2. Testing with Load:
   • Use the second XT30-to-Banana power cable pair to apply loads between VOUT and GND.
   • Under heavy-load conditions, use caution. The KTS1693 IC may become hot; avoid skin contact.
   • Use multimeters and an oscilloscope to make DC and transient measurements as desired.
3. To check the KTS1693 OVP (over voltage protection) functionality:
   • Slowly increase the power-supply voltage VIN from 5V to 6V.
   • Check that the output voltage VOUT drops to zero once the input voltage VIN exceeds the Internal Overvoltage Trip level or 5.95V typical.
4. To check the KTS1693 OCP (over current protection) functionality:
   • Slowly increase the E-load output current IOUT from 4.5A to 5.5A.
   • Check that the output voltage VOUT drops to zero once the output current IOUT exceeds about 5.0A typical.
5. To measure the KTS1693 OVP/OCP switch on-resistance RDS(ON):
   • Measure the output current between the VOUT terminal and the load.
   • Measure the voltage between the test points KVin and KVout (Kelvin connections).
   • The switch resistance can be calculated with the formula: RDS(ON) = (VKVin – VKVout) / IOUT.

Troubleshooting

̅A̅C̅̅O̅K̅ has an Absolute Maximum Rating of 6V.

̅E̅N̅ = VIO does not disable the switch.| VIO supply is off or not connected.| Connect and enable a VIO pull-up supply.

̅E̅N̅ has an Absolute Maximum Rating of 6V.
