GENERAL DESCRIPTION
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 DESCRIPTION
| 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 |
Packaging & Shipping
Standard export packaging available. Customers can choose from cartons, wooden cases, and wooden pallets according to their requirements.
