Pinout

Pin	Name	Type	Function
1	GND	power_in	Ground and power ground pin (also listed as PGND for the MSOP) that needs a short direct PCB path to the ground plane the exposed pad is soldered to.
2	BST1	passive	Boot-strapped floating supply for the high-side NMOS gate drive, connected to SW1 through a 22nF capacitor placed as close to the part as possible.
3	SW1	passive	Switch pin connected to one side of the inductor, with PCB traces kept as short and wide as possible to reduce EMI and parasitic resistance.
4	PVIN	power_in	Power input for the buck-boost converter, needing a 4.7µF or larger bypass capacitor to the ground plane placed close to the IC (typically 47µF or larger bulk capacitance if powered through long leads or a high-ESR source).
5	VIN	power_in	Input voltage for the VCC regulator, needing a minimum 1µF ceramic decoupling capacitor to the ground plane.
6	RUN	input	Run comparator input that enables the converter above 1.05V and enters standby mode (reference on, no switching) above 0.6V typical, and can be tied to a resistor divider from VIN to set an accurate VIN start threshold.
7	VCC	power_out	Output of the internal 4V regulator that supplies the internal circuitry, needing a minimum 4.7µF ceramic bypass, not to be back-driven, and able to power external circuitry only up to a 2mA peak load.
8	MPPC	input	Maximum power point control programming input, connected to a resistor divider from VIN to ground (reducing inductor current if the divider falls below 1.0V typical) or tied to VCC if unused, and very noise sensitive.
9	FB	input	Feedback input to the error amplifier, connected to a resistor divider from VOUT to ground to set VOUT = 1.00V•(1+R1/R2) over a 1.0V to 25V range, and very noise sensitive.
10	ILIM	input	Current limit select pin, where low (ground) sets the average inductor current limit to 250mA minimum and high (tie to VCC) sets it to 660mA minimum, and it can be dynamically driven by a logic signal.
11	MODE	input	Mode select pin where low (ground) enables automatic Burst Mode operation and high (tie to VCC) selects fixed-frequency PWM operation, with an internal 3MΩ pull-down once switching is enabled.
12	EXTVCC	power_in	Second input to the internal VCC regulator, tied to VOUT or another voltage between 3V and 25V (4.7µF decoupling recommended unless tied to the VOUT capacitor), and grounded if not used.
13	PGOOD	output	Open-drain power-good output that pulls to ground when FB drops too far below its regulated voltage, requires a pull-up resistor to a positive supply, and is forced low in shutdown or UVLO if VIN or EXTVCC is present.
14	VOUT	power_out	Output voltage of the converter, needing a minimum 4.7µF ceramic capacitor from this pin to the ground plane.
15	BST2	passive	Boot-strapped floating supply for the high-side NMOS gate drive, connected to SW2 through a 22nF capacitor placed as close to the part as possible.
16	SW2	passive	Switch pin connected to the other side of the inductor, with PCB traces kept as short and wide as possible to reduce EMI and parasitic resistance.
17	GND	power_in	Exposed pad that is ground, must be soldered to the PCB ground plane, and serves as a power ground connection and as a means of conducting heat away from the die.
