PIN | I/O | DESCRIPTION | |
---|---|---|---|
NAME | NUMBER | ||
FSW | 1 | I | The switching frequency is programmed by a resister between this pin and the SW pin. |
VCC | 2 | O | Output of the internal regulator. A ceramic capacitor of more than 1.0 µF is required between this pin and ground. |
FB | 3 | I | Output voltage feedback |
COMP | 4 | O | Output of the internal error amplifier. The loop compensation network should be connected between this pin and the GND pin. |
GND | 5 | PWR | Ground |
VOUT | 6 | PWR | Boost converter output |
EN | 7 | I | Enable logic input. Logic high level enables the device. Logic low level disables the device and turns it into shutdown mode. |
ILIM | 8 | O | Adjustable switching peak current limit. An external resister should be connected between this pin and the GND pin. |
VIN | 9 | I | IC power supply input |
BOOT | 10 | O | Power supply for high-side MOSFET gate driver. A capacitor must be connected between this pin and the SW pin |
SW | 11 | PWR | The switching node pin of the converter. It is connected to the drain of the internal low-side power MOSFET and the source of the internal high-side power MOSFET. |
