4 Pin Configuration and Functions

GUID-20231128-SS0I-FGT8-R2TW-JBF3VSLWQDJB-low.svg Figure 4-1 13-Pin RYH VQFN Package (Top View)
Table 4-1 Pin Functions
PIN I/O DESCRIPTION
NAME NUMBER
VIN 1 I IC power supply input
EN/UVLO 2 I Enable logic input and programmable input voltage undervoltage lockout (UVLO) input. Logic high level enables the device. Logic low level disables the device and turns it into shutdown mode. The converter start-up and shutdown levels can be programmed by connecting this pin to the supply voltage through a resistor divider.
ISEL 3 I Scale the ISO FET to improve input average current limit accuracy and adjust peak switching current limit value.

ISEL = low when setting Ilimit ≤ 750mA

ISEL = high, when setting Ilimit > 750mA
VOUT 4 PWR Boost converter output
VP 5 PWR Drain of the ISO MOSFET
SW 6 PWR The switching node pin. It is connected to the drain of the internal low-side power MOSFET and the source of the internal ISO power MOSFET.
PGND 7 PWR Power ground of the IC
FB 8 I Output voltage feedback pin. Connect to the center tape of a resistor divider to program the output voltage.
COMP 9 O Output of the internal error amplifier. Connect the loop compensation network between this pin and the AGND pin.
ILIM 10 I Input average current limit setting pin. Use a resistor between this pin and AGND to set the desired input average current limit threshold.
VCC 11 O Output of the internal regulator. A ceramic capacitor of more than 1μF is required between this pin and AGND.
AGND 12 PWR Analog ground of the IC
BOOT 13 O Power supply for ISO MOSFET gate driver. A ceramic capacitor of more than 0.47μF must be connected between this pin and the SW pin.
