Monolithic Power Systems · DC-DC Converters · QFN-16(3x3)
MPQ1530DQ-AEC1-LF-Z from Monolithic Power Systems, in a QFN-16(3x3). 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 | SW | output | Step-up converter power switch node, the drain of the internal 250mΩ N-channel MOSFET, with an inductor connected from the input source to SW and a rectifier from SW to the main output. |
| 2 | CT | passive | Timing capacitor for power-supply soft-start and power-on sequencing, where a capacitor from CT to GND sets the soft-start and turn-on delay periods (10nF gives a 6ms soft-start period). |
| 3 | RDY | output | Regulators-not-ready flag that is high during startup and pulled low once all FB voltages exceed 80% of their thresholds, and a fault persisting for more than approximately 6ms (CT = 10nF) shuts down the entire chip. |
| 4 | FB1 | input | Step-up converter feedback input and inverting input of the internal error amplifier, with a resistive divider from the step-up output setting the output voltage. |
| 5 | COMP | passive | Step-up converter compensation node, the output of the error amplifier, which requires a series RC network to compensate the control loop. |
| 6 | IN | power_in | Internal power input supplying the MPQ1530, which must be bypassed to PGND with a 10μF or greater capacitor; operating input range is 2.7V to 5.5V. |
| 7 | GND | power_in | Signal ground for the control circuitry, to be connected to PGND at one point as close to the IC as possible. |
| 8 | REF | power_out | 1.25V reference voltage output, which must be bypassed to GND with a 0.1μF or greater capacitor and connects to the low-side resistor of the negative linear regulator feedback string. |
| 9 | FB2 | input | Negative linear regulator feedback input with a regulation threshold of GND, with the feedback resistor string connected between GL and REF. |
| 10 | FB3 | input | Positive linear regulator feedback input with a regulation threshold of 1.25V, with the feedback resistor string connected between GH and GND. |
| 11 | EN | input | On/off control input where driving EN high turns the MPQ1530 on and driving it low immediately disables all outputs; connect EN to IN for automatic startup. |
| 12 | GL | power_out | Negative linear regulator output that supplies up to 20mA to the load and must be bypassed to GND with a 1μF or greater, low-ESR ceramic capacitor. |
| 13 | IN2 | power_in | Negative linear regulator input driven by an inverting charge pump from SW, which can go as low as -20V; for the QFN package the exposed pad must be connected to this pin. |
| 14 | GH | power_out | Positive linear regulator output that supplies as much as 20mA to the load and must be bypassed to GND with a 1μF or greater, low-ESR ceramic capacitor. |
| 15 | IN3 | power_in | Positive linear regulator input driven by a doubling, tripling, or quadrupling charge pump from SW, which can go as high as 38V. |
| 16 | PGND | power_in | Power ground that is the source of the internal 250mΩ N-channel MOSFET switch and must be connected to GND as close to the MPQ1530 as possible. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
