TPS92692QPWPRQ1 from Texas Instruments, in a HTSSOP-20-EP. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Input supply for internal regulators (4.5 V to 65 V operating range); bypass with 10-Ω series resistor and 10-nF capacitor to GND. |
| 2 | VREF | power_in | VREF (5 V) bias supply pin; locally decouple to GND using 2.2-μF to 4.7-μF ceramic capacitor located close to controller. |
| 3 | FLT | output | Open-drain fault indicator (active low) for overvoltage, undervoltage, overcurrent (14 × V(CSP-CSN) > 1.5 × VIADJ), or switch current limit (VIS > 250 mV) conditions. |
| 4 | SS | input | Soft-start programming pin; connect capacitor to GND to extend startup time or short to GND to disable switching. |
| 5 | DM | input | Spread spectrum modulation frequency (fm) programming pin; connect capacitor to GND to set modulating frequency or directly to GND to disable spread spectrum. |
| 6 | RT | input | Oscillator frequency programming pin (80 kHz to 800 kHz); connect resistor to GND to set switching frequency or couple external clock via 100-nF capacitor for synchronization. |
| 7 | COMP | output | Transconductance error amplifier output; connect compensation network (resistor and capacitor) to achieve desired closed-loop response. |
| 8 | IMON | output | LED current report pin with output relationship VIMON = 14 × ILED × RCS; bypass with 1-nF ceramic capacitor to GND. |
| 9 | IADJ | input | LED current reference input with analog dimming range 140 mV to 2.25 V or connect to VCC via 100-kΩ resistor to set internal reference to 2.42 V and current sense threshold to 170.7 mV. |
| 10 | DIM/PWM | input | External analog (1 V to 3 V) or direct PWM dimming input setting LED current duty cycle 0% to 100%; connect to VREF when unused. |
| 11 | RAMP | input | PWM generator frequency programming input (100 Hz to 2000 Hz); connect capacitor to GND to set ramp frequency or 249-kΩ resistor to GND to disable PWM generator. |
| 12 | PDRV | output | Series dimming P-channel FET gate driver output (maximum ±50 mA pulsed <10 μs); connect to external P-channel MOSFET gate for PWM dimming and fault disconnect. |
| 13 | CSN | input | Current sense amplifier negative input (−); connect directly to negative node of LED current sense resistor RCS. |
| 14 | CSP | input | Current sense amplifier positive input (+) with maximum ±0.3 V differential to CSN; connect directly to positive node of LED current sense resistor RCS. |
| 15 | OV | input | Output voltage monitoring input; connect resistor divider from output voltage to GND to set overvoltage (>1.228 V) and undervoltage (<100 mV) protection thresholds. |
| 16 | SLOPE | input | Slope compensation ramp input; connect resistor to GND to set desired slope compensation based on inductor value and input/output voltages. |
| 17 | GND | power_in | Analog and power ground connection pin; connect to circuit ground and thermal pad via multiple vias for proper heat dissipation and return path. |
| 18 | IS | input | Switch current sense input; connect to switch sense resistor RIS to set current limit threshold based on internal 250 mV reference. |
| 19 | GATE | output | N-channel MOSFET gate driver output (maximum ±500 mA pulsed <20 ns); connect to gate of external main switching N-channel MOSFET. |
| 20 | VCC | power_in | VCC (7.5 V) bias supply pin; locally decouple to GND using 2.2-μF to 4.7-μF ceramic capacitor located close to controller. |
| 21 | PAD | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

Package_SO:TSSOP-20-1EP_4.4x6.5mm_P0.65mm_EP2.15x3.35mm - 3D model: HTSSOP-20-EP, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.2 mm nominal TSSOP height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
