Monolithic Power Systems · LED Drivers · SOIC-8-EP
MP24833-AGN-Z from Monolithic Power Systems, in a SOIC-8-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 | VDD | power_in | Supply input that operates from a 4.5V-to-55V unregulated input (with respect to VSS), and an input capacitor is needed to prevent large voltage spikes at the input. |
| 2 | VSS | power_in | Power return and voltage reference for the regulated output, to be connected to the lowest potential in the circuit (typically the Schottky rectifier anode); the exposed pad is also connected to VSS. |
| 3 | OVP | input | Over-voltage protection input programmed by a voltage divider, where the switch turns off at the 2.43V shutdown threshold and normal operation requires programming from 0.2V to 2.43V. |
| 4 | FB | input | LED current feedback input that senses the current across the sensing resistor connected between FB and VSS, with a regulation voltage of 0.2V. |
| 5 | EN/DIM | input | On/off and dimming control input referenced to INGND that turns the chip on above 0.67V, supports analog dimming from 0.67V to 1.35V, and PWM dimming at 100Hz-2kHz with an amplitude greater than 1.5V. |
| 6 | INGND | power_in | Input ground reference that serves as the reference for the EN/DIM signal. |
| 7 | BST | passive | Bootstrap pin where a ceramic capacitor of 100nF or larger is connected between SW and BST to form a floating supply for the power switch driver. |
| 8 | SW | output | Switch output that is the source of the internal MOSFET, connected to the power inductor and the cathode of the rectifier diode. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
