2. Setup Condition

a. Adjust the power supply VIN with recommended operating range (2.5V to 28V).

b. Connect proper load to LN and LP terminals.

c. Apply external PWM signal with frequency range, 20kHz to 100kHz.

d. Apply EN voltage (5V or 3.3V tolerance).

e. Current direction is controlled by MODE pin, L=reverse, H=forward. MODE=H as default.

f. The full-scale current reference value is set by R11. If the full-scale current reference is set, the

actual output current sent to the error amplifier can be further controlled by applying a PWM input signal

to PWM. Refer to the DS for details.

3. Monitors

a. FT on the evaluation board indicates Over Temperature Protection and Over Current Protection.

This is an open drain output with onboard 10k ohm pull-up resistor.
