LT1767EMS8E#TRPBF
Analog Devices · DC-DC Converters · MSOP-8-EP
LT1767EMS8E#TRPBF from Analog Devices, in a MSOP-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 | BOOST | power_in | Provides a drive voltage higher than the input voltage to the internal NPN power switch so the switch can saturate; without it the typical switch voltage loss would be about 1.5V. |
| 2 | VIN | power_in | Collector of the on-chip power NPN switch and supply pin for the internal circuitry and regulator; the bypass capacitor and catch diode must be kept close to this pin. |
| 3 | SW | output | Emitter of the on-chip power NPN switch, driven up to the input voltage during switch on time; negative voltage during switch off must be clamped by an external catch diode with VBR < 0.8V. |
| 4 | GND | power_in | Reference for the regulated output, connected to the internal tab and to the exposed pad; it should be soldered to a large copper area to improve thermal resistance. |
| 5 | SHDN | input | Shutdown pin that turns the regulator off and reduces input drain current to a few microamperes; its 1.33V threshold can serve as an accurate undervoltage lockout, and floating or pulling it high runs the regulator. |
| 6 | FB | input | Feedback pin that sets the output through an external divider generating 1.2V at the pin on the adjustable part; an impedance below 5kΩ at this pin is needed for the current limit foldback when FB is below 0.5V. |
| 7 | VC | passive | Output of the error amplifier and input of the peak switch current comparator, normally used for frequency compensation; it sits at about 0.35V at very light loads and 0.9V at maximum load, and can be driven to ground to shut off the output. |
| 8 | SYNC | input | Synchronizes the internal oscillator to an external logic signal with a 20% to 80% duty cycle over a range from the initial operating frequency up to 2MHz; it should be grounded when not in use. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
