User-Supplied Equipment
Required Equipment
- Bench Power Supply for VIN – 5V and 0.5A/2A, as needed for the intended application.
- Digital Multi meter – one or more, used to measure input/output voltages and currents.
Optional Equipment
- Oscilloscope – for dynamic testing of voltages (and currents with a current probe, if available).
- Load – either an e Load, power resistors, or an actual system load.
- Additional Digital Multi meters

Quick Start Procedures
- Set Jumper to default: EN = VIN (High)
- Connect one pair of Banana-to-clip power cables to the test points at VIN and GND (right edge of EVAL Kit).
- 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 Banana to clip power cables to the VIN bench supply.
- Turn on the VIN bench supply and very slowly ramp its voltage to an appropriate voltage of 4.5V. While ramping VIN slowly, use the bench supply’s output current indication (or a digital multi meter) 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.
- With valid VIN voltage, use a digital multi meter to check the output voltage between the KVOUT and GND terminals on the EVAL Kit. It should be nearly the same as the input voltage.
- Use a digital multi meter to check the no-load supply current at VIN. Consult the KTS1601 datasheet for the expected current range at the VIN voltage condition in use. For conditions of VIN = 4.5V, EN = VIN,and no-load, it should be close to 6A.

Additional Test Procedures
- Testing with load and measure the KTS1601 load switch on-resistance RDS(ON)
a. Use power cable pair to apply loads, for example 10Ω, from VOUT to GND.
b. Use multi meters and an oscilloscope to make DC and transient measurements as desired.
c. Measure the output current between the VOUT terminal and the resistive load.
d. Measure the voltage between the test points KVIN and KVOUT (VIN/VOUT Kelvin connections).
e. The switch resistance can be calculated with the formula: RDS(ON) = (VKVIN – VKVOUT)/output current.
