PRODUCTION DATA
PIN | I/O | DESCRIPTION | |
---|---|---|---|
NUMBER | NAME | ||
A1 | FB | I | Output voltage feedback. A resistor divider connecting to this pin sets the output voltage. |
A2 | COMP | O | Output of the internal error amplifier. The loop compensation network must be connected between this pin and GND. |
A3 | NC | I | No connection. Tie directly to VIN pin. Do not connect with GND or leave it floating. |
A4 | MODE | I | Operation mode selection pin. MODE = low, the device works in auto PFM mode with good light load efficiency. MODE = high, the device is in forced PWM mode and keeps the switching frequency constant across the whole load range. |
B1, B2, B3 | GND | - | Ground |
B4 | EN | I | Enable logic input. Logic high level enables the device. Logic low level disables the device and turns it into shutdown mode. |
C1, C2, C3 | SW | PWR | The switching node pin of the converter. It is connected to the drain of the internal low-side FET and the source of the internal high-side FET. |
C4 | BST | O | Power supply for the high-side FET gate driver. A capacitor must be connected between this pin and the SW pin. |
D1, D2, D3 | VOUT | PWR | Boost converter output |
D4 | VIN | I | IC power supply input |
