The MT3608 is a constant frequency, 6-pin SOT23 current mode step-up converter intended for small, low power applications. The MT3608 switches at 1.2MHz and allows the use of tiny, low cost capacitors and inductors 2mm or less in height. Internal soft-start results in small inrush current and extends battery life.
The MT3608 features automatic shifting to pulse frequency modulation mode at light loads. The MT3608 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The MT3608 is available in a small 6-pin SOT-23 package.
| Pin Name | Pin Number | Description |
|---|---|---|
| SW | 1 | Power Switch Output. SW is the drain of the internal MOSFET switch. Connect the power inductor and output rectifier to SW. SW can swing between GND and 28V. |
| GND | 2 | Ground Pin |
| FB | 3 | Feedback Input. The FB voltage is 0.6V. Connect a resistor divider to FB. |
| EN | 4 | Regulator On/Off Control Input. A high input at EN turns on the converter, and a low input turns it off. When not used, connect EN to the input supply for automatic startup. |
| VIN | 5 | Input Supply Pin. Must be locally bypassed. |
| NC | 6 | No Connect |
