MPQ3367AGR-AEC1-Z from Monolithic Power Systems, in a QFN-24(4x4). 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 | DIM | input | PWM signal input for brightness control; DIM is pulled low internally and a 100Hz to 20kHz PWM signal is recommended. |
| 2 | MIX/AD | passive | Dimming-mode setting pin with an 18μA current-source output; below 0.3V selects mix dimming, 0.5V to 0.8V selects PWM dimming, 1.0V to 1.3V selects analog dimming, and floating uses the internal MODE register. |
| 3 | FREQ/SYNC | input | Switching frequency is set by a resistor to GND or the boost frequency is synchronized by an external clock; float this pin if the frequency is set by FSW1:0. |
| 4 | EN | input | IC enable pin; pull high to enable the IC and pull low to shut it down. |
| 5 | SCL/PSE | bidirectional | I2C clock pin; connect to SDA/PSE and pull up between 0.75V and 1V to enable phase-shift PWM dimming, and do not float the pin if unused (tie to a high level or GND). |
| 6 | SDA/PSE | bidirectional | I2C data pin; connect to SCL/PSE and pull up between 0.75V and 1V to enable phase-shift PWM dimming, and do not float the pin if unused (tie to a high level or GND). |
| 7 | COMP | passive | Compensation pin for the boost converter loop. |
| 8 | FF | output | Fault flag pin; open drain during normal operation and pulled low when a fault occurs. |
| 9 | ISET | passive | LED current setting pin; a current-setting resistor from ISET to GND configures the current in each LED string. |
| 10 | AGND | power_in | Analog ground pin. |
| 11 | LED6 | passive | LED string 6 current input; connect the string 6 cathode to this pin, or tie to GND if unused. |
| 12 | LED5 | passive | LED string 5 current input; connect the string 5 cathode to this pin, or tie to GND if unused. |
| 13 | LED4 | passive | LED string 4 current input; connect the string 4 cathode to this pin, or tie to GND if unused. |
| 14 | LED3 | passive | LED string 3 current input; connect the string 3 cathode to this pin, or tie to GND if unused. |
| 15 | LED2 | passive | LED string 2 current input; connect the string 2 cathode to this pin, or tie to GND if unused. |
| 16 | LED1 | passive | LED string 1 current input; connect the string 1 cathode to this pin, or tie to GND if unused. |
| 17 | PGND | power_in | Step-up converter power ground pin. |
| 18 | SW | passive | Drain pin of the internal low-side MOSFET; connect the power inductor to SW, with VSW rated -0.5V to 50V and -1.0V for less than 100ns. |
| 19 | OVP | input | Over-voltage protection setting pin; a resistor divider from VOUT to OVP and from OVP to GND sets the OVP threshold. |
| 20 | STH | passive | Short LED protection threshold pin with an 18μA current-source output; a resistor sets its voltage, and the pin should float to use the internal TH_S1:0 threshold. |
| 21 | ADR | passive | IC address setting pin with an 18μA pull-up current; floating sets 0x38, below 0.4V sets 0x3A, and 0.4V to 1.4V sets 0x39. |
| 22 | VCC | power_out | 5V LDO output that powers the internal logic and gate driver; place a ceramic capacitor as close to this pin as possible. |
| 23 | SD | output | External disconnect PMOS gate drive pin used to turn off the external PMOS if a fault occurs; float the pin if it is not used. |
| 24 | VIN | power_in | Power supply input for the IC; recommended operating supply range is 3.5V to 36V. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
