CN5816 from ShangHai Consonance Elec, in a SSOP-10-150mil. 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 SHDN input Active-high chip shutdown input. Drive high (VIH >= 2.3V) to put CN5816 into shutdown; in shutdown the internal blocks including the 5V regulator are disabled and quiescent current is extremely low. Drive low (VIL <= 0.5V) for normal operation. PWM dimming is done by applying the PWM signal directly to this pin (each high-to-low transition retriggers the ~9.5ms soft start).
2 COMP output Loop frequency compensation pin. Connect the external frequency-compensation network (R3 series with C3) from this pin to GND. This is the transconductance error amplifier output used to tune loop dynamics.
3 OVP input Output over-voltage protection feedback input. When OVP rises above 1.283V the internal PWM controller shuts off the external N-channel MOSFET; the PWM resumes only after OVP falls below 1.219V. Set the OVP trip via an R1/R2 divider from VOUT: VOUT = 1.283 x (1 + R1/R2). Bias current is +/-100nA.
4 CSP input LED current-sense positive input. Connect to the current-inflow side of the external LED current-sense resistor RCS. The chip regulates LED current using a 120mV threshold: ILED = 120mV / RCS.
5 CSN input LED current-sense negative input. Connect to the current-outflow side of the external LED current-sense resistor RCS. Forms the high-side differential sense pair with CSP; regulation threshold is 120mV.
6 VIN power_in Input supply. Operating range 4.5V to 32V (absolute max 36V). Requires an input decoupling capacitor to GND close to the pin.
7 VCC power_out 5V internal LDO output. Powers internal low-voltage circuitry and the MOSFET gate driver, and can source up to 4mA to external circuitry. Requires at least 4.7uF to GND. Regulates to ~5V when VIN is 5.5V-32V; below 5.5V the output tracks lower.
8 DRV output Gate-drive output for the external N-channel MOSFET. High level is 5V (from VCC). Source capability 0.8A, sink capability 1.5A; typical rise/fall times 32ns/25ns into a 2nF gate.
9 GND power_in Ground / input supply return. Route signal ground (R2, C3, C4, C5, and this pin) separately from power ground and tie together at a single system-ground point.
10 ISW input Inductor current sense input. Senses the voltage across an RSW resistor from the external MOSFET source to GND for current-mode control and cycle-by-cycle over-current protection. Over-current threshold VCS(OC) is 180mV typical (162-198mV). An RC filter (R4 <= 2k with C5, ~100ns time constant) is recommended.
