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 | VBAT | power_in | Battery/IC power supply input. Recommended operating range 2.7V to 5.5V (absolute max 7V). Bypass with a low-ESR ceramic capacitor near the pin. |+| 2 | EN1 | input | Power control / enable pin 1. Logic input with VthL <= 0.4V and VthH >= 1.4V (max 5.5V), input current ~8.3µA at 2.5V. Used with EN2 and PWM to select which of LED1-4 current drivers are enabled and can be driven with a PWM signal for power-control PWM dimming. |+| 3 | EN2 | input | Power control / enable pin 2. Logic input with VthL <= 0.4V and VthH >= 1.4V (max 5.5V). Combines with EN1/PWM to enable LED current drivers and supports power-control PWM dimming (100Hz-1kHz). |+| 4 | GND | power_in | Analog ground for the DC/DC converter block. Tied together with pins 7 and 10 internally; connect to the ground plane. |+| 5 | PWM | input | PWM dimming input for the current drivers (also acts as an enable). Logic thresholds VthL <= 0.4V, VthH >= 1.4V. Typical PWM frequency 100Hz to 10kHz for current-driver PWM control. |+| 6 | ISET | input | LED current programming pin. Connect a resistor (RISET) to GND to set nominal LED current: Inormal = 20mA x (24kΩ/RISET). ISET voltage typically 0.6V; do not add capacitance (may oscillate). |+| 7 | GND | power_in | Ground return for the ISET resistor. Route RISET's ground leg directly to this pin to preserve current-set accuracy. |+| 8 | LED1 | input | Current sink for LED string 1 (channel 1). Regulated to VLED = 0.5V typ. Maximum 25mA per channel; LED terminal over-voltage protection at 11.5V typ. Absolute max 25V. Leave OPEN if unused. |+| 9 | LED2 | input | Current sink for LED string 2. Same specifications as LED1 (VLED = 0.5V typ, 25mA max, 11.5V LED OVP, 25V abs max). |+| 10 | GND | power_in | Ground for the current-driver block. Internally connected to pins 4 and 7. |+| 11 | LED3 | input | Current sink for LED string 3. Same specifications as LED1 (VLED = 0.5V typ, 25mA max, 11.5V LED OVP, 25V abs max). |+| 12 | LED4 | input | Current sink for LED string 4. Same specifications as LED1 (VLED = 0.5V typ, 25mA max, 11.5V LED OVP, 25V abs max). |+| 13 | TEST | input | Factory test input, pulled down internally with 100kΩ to GND. Leave open or tie to GND in application. |+| 14 | TESTO | output | Factory test output. Leave unconnected in application. |+| 15 | NC | unconnected | No connect. Leave floating or tie to GND. |+| 16 | SW | output | Drain of the integrated 28V N-channel switching MOSFET (boost switch node). Absolute max 30.5V. RDS(on) ~0.24Ω typ at Isw = 100mA. Pins 16, 17, 18 are ganged internally; tie to the inductor/SBD anode node. |+| 17 | SW | output | Boost switch node (paralleled with pins 16 and 18) to lower conduction resistance and improve heat dissipation. |+| 18 | SW | output | Boost switch node (paralleled with pins 16 and 17). |+| 19 | VDET | input | Boost output sense input for external SBD-open detect and output over-voltage protection. SBD-open triggers when VDET < 0.1V; OVP set at 25.5V typ (25.0-26.0V). Absolute max 50.5V. |+| 20 | NC | unconnected | No connect. Leave floating or tie to GND. |+| 21 | PGND | power_in | Power ground / source return for the integrated switching MOSFET. Route directly to input/output capacitor grounds; separated from analog GND inside the IC. |+| 22 | PGND | power_in | Power ground / source return for the integrated switching MOSFET (paralleled with pin 21). |+| 23 | NC | unconnected | No connect. Leave floating or tie to GND. |+| 24 | TRSW | output | Internal switching-MOSFET gate node. A capacitor to PGND may be connected here to soften the SW slew rate and reduce switching noise at the cost of efficiency. |+| EP | GND | power_in | Exposed thermal pad on the package underside. Must be connected to GND for both thermal dissipation and electrical grounding. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | ROHM Semicon |+| Package | VQFN-24-EP(4x4) |+| Category | LED Drivers |+| Pins | 25 |++## Ordering variants++Same part, different packaging or reel option.++- `BD6586MUV-E2`++## CAD (KiCad official)++- Symbol: `BD6586MUV-E2`+- Footprint: `Package_DFN_QFN:QFN-24-1EP_4x4mm_P0.5mm_EP2.7x2.7mm`+- 3D model: VQFN-24-EP(4x4) (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [ROHM Semicon datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588921791540563968) (None pp, sha256 `788a6aa7f1f338c9`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
