| Pin # | Name | Function | | :--- | :--- | :--- | | 1 | FB2 | Feedback input for Channel 2. Connects to a resistor divider from VOUT2. | | 2 | COMP2 | Compensation pin for Channel 2 (connects to RC network for loop stability). | | 3 | SS2 | Soft-start capacitor for Channel 2. Capacitor value sets startup time. | | 4 | VCC | Supply voltage input (typically 5V or 12V). Bypass with 0.1µF & 10µF. | | 5 | EN2 | Enable for Channel 2. High (>2V) = Enabled. Low (<0.8V) = Disabled. | | 6 | GND | Ground reference. | | 7 | UGATE2 | High-side gate drive output for Channel 2 (connects to top MOSFET). | | 8 | LGATE2 | Low-side gate drive output for Channel 2 (connects to sync MOSFET). | | 9 | PHASE2 | Switch node for Channel 2 (connects to source of high-side MOSFET). | | 10 | LGATE1 | Low-side gate drive output for Channel 1. | | 11 | UGATE1 | High-side gate drive output for Channel 1. | | 12 | PHASE1 | Switch node for Channel 1. | | 13 | EN1 | Enable for Channel 1. | | 14 | COMP1/REFIN | Compensation for Channel 1 or external reference input. | Connects to a resistor divider from VOUT2
The is ideal when you need two independent rails (e.g., 1.2V and 2.5V) from a single 12V supply without the complexity of I2C or sequencing.
