# CMP6793RE

**coileasy** · Transformer Drivers · ESOP-8

CMP6793RE from coileasy, in a ESOP-8. 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 | CLK | input | Oscillator clock frequency adjust input. Floating or tied to GND gives the default 240 kHz center switching frequency; an external resistor to GND programs Fsw per Fsw(kHz)=5326/Rclk(kΩ). Absolute max input voltage 5.5 V. |
| 2 | GND | power_in | Chip ground reference for internal analog and logic circuitry. |
| 3 | VCC | power_in | Main supply input (VIN). Recommended operating range 6.5 V-30 V (abs max 34 V). Place a ≥1 µF (typ. 10 µF/25 V) decoupling capacitor between VIN and GND as close to the pin as possible. |
| 4 | EN | input | Enable input. Floating or high enables the device (internal pull-up resistor); a logic low disables it. VEN(ON) typ. 1.2 V, hysteresis typ. 1.0 V. Abs max 34 V. |
| 5 | VD2 | output | Transformer drive output 2 (half-bridge output, complementary to VD1). Drives one leg of the integrated PMOS/NMOS bridge into the transformer primary. Abs max 34 V, peak current 1.6 A, current-limit typ. 670 mA. |
| 6 | NC | unconnected | No internal connection. Leave floating or tie to a copper pour for mechanical support. |
| 7 | NC | unconnected | No internal connection. Leave floating or tie to a copper pour for mechanical support. |
| 8 | VD1 | output | Transformer drive output 1 (half-bridge output, complementary to VD2). Drives one leg of the integrated PMOS/NMOS bridge into the transformer primary. Abs max 34 V, peak current 1.6 A, current-limit typ. 670 mA. |
| 9 | EP | power_in | Exposed thermal pad. Internally connected to GND; solder to a large ground copper area for improved thermal dissipation. Not intended as an electrical connection point beyond GND. |

## CAD (KiCad official)

- Symbol: `CMP6793RE`
- Footprint: `Package_SO:SOIC-8-1EP_3.9x4.9mm_P1.27mm_EP2.29x3mm`
- 3D model: ESOP-8 (KiCad packages3D, STEP)
- 3D model files: `cmp6793re-etched.step` / `cmp6793re-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cmp6793re.step` / `cmp6793re.glb` are the bare package body.
