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
