TPS60230RGTR from Texas Instruments, in a VQFN-16-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	ISET	input	Connect a resistor between this pin and GND to set the maximum current through the LEDs. Recommended ISET pin current range 4 to 130 µA; reference voltage 580-620 mV (EN2=EN1=1).
2	D5	input	Current sink input for LED5. Connect the cathode of the white LED to this input. Recommended maximum current per current sink is 25 mA.
3	D4	input	Current sink input for LED4. Connect the cathode of the white LED to this input. Recommended maximum current per current sink is 25 mA.
4	D3	input	Current sink input for LED3. Connect the cathode of the white LED to this input. Recommended maximum current per current sink is 25 mA.
5	D2	input	Current sink input for LED2. Connect the cathode of the white LED to this input. Recommended maximum current per current sink is 25 mA.
6	D1	input	Current sink input for LED1. Connect the cathode of the white LED to this input. Recommended maximum current per current sink is 25 mA.
7	PGND	power_in	Power ground. Connect with analog ground (GND).
8	VOUT	power_out	Charge pump output. Connect the output capacitor (1 µF) and the anodes of the LEDs to this pin. Overvoltage limit 5.5 V.
9	C2+	passive	Positive terminal of flying capacitor C2. Connect a 0.22-0.47 µF ceramic flying capacitor between C2+ and C2-.
10	C1+	passive	Positive terminal of flying capacitor C1. Connect a 0.22-0.47 µF ceramic flying capacitor between C1+ and C1-.
11	C1-	passive	Negative terminal of flying capacitor C1. Connect a 0.22-0.47 µF ceramic flying capacitor between C1+ and C1-.
12	C2-	passive	Negative terminal of flying capacitor C2. Connect a 0.22-0.47 µF ceramic flying capacitor between C2+ and C2-.
13	VIN	power_in	Supply voltage input. Operating range 2.7 V to 6.5 V; requires a 1 µF input capacitor to ground. Absolute max 7 V.
14	GND	power_in	Analog ground.
15	EN1	input	Enable input 1. Logic high enables the converter; logic low forces shutdown (<1 µA) if EN2 is also tied to GND. Together with EN2 selects x1/x1.5 mode and PWM dimming. VIH = 1.3 V min, VIL = 0.3 V max.
16	EN2	input	Enable input 2 / PWM dimming input. An applied PWM signal reduces LED current as a function of duty cycle. EN1 and EN2 can be tied together for PWM dimming between 0 mA and the ISET-programmed maximum, or used for 4-step digital dimming. PWM frequency 0-50 kHz.
17	PowerPAD	power_in	Exposed thermal pad on package underside. Connect to PGND and GND for thermal dissipation and electrical grounding.
