HG1507MDT-ADJ
HGSEMI · DC-DC Converters · TO-252-4
HG1507MDT-ADJ from HGSEMI, in a TO-252-4. 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 | VIN | power_in | Supply input pin requiring a 4.5V to 40V DC supply, with a large capacitor placed between this pin and ground to suppress supply noise. |
| 2 | OUTPUT | power_out | Power switch output pin, a switching node that supplies the output load (rated -0.3V to VIN). |
| 3 | GND | power_in | Ground pin, to be placed in the layout on the output-capacitor ground path outside the Schottky diode loop so switching current spikes do not add noise; the metal tab is also GND. |
| 4 | FEEDBACK | input | Voltage feedback pin that monitors the output through an external resistor divider, with a feedback threshold voltage of 1.23V. |
| 5 | ON_OFF | input | Enable pin where a low level turns the chip on, a high level (above about 1.4V) turns it off, and it defaults to low when floating. |
