Power Requirements a. Power supply range: 2.5V to 28V, 5A Max. AGND PWM FT AGND MODE AGND VIN EN LP R11 U1 GND LN MPS MP6519 Demo Board EV6519-Q-00A Figure 5 — EV6519-Q-00A Bird’s-eye View 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.
