MT3608L Step-Up Converter IC | 1.2MHz Boost Regulator 2.5A – SOT23-6

The MT3608L is a high-efficiency 1.2MHz step-up (boost) DC-DC converter IC designed for compact, low-power applications. With its integrated 80mΩ power MOSFET, adjustable over-current protection, and wide 2.2V to 16V input range, this IC delivers exceptional performance for battery-powered devices and portable electronics.

Capable of producing output voltages up to 20V with efficiency levels reaching 93%, the MT3608L operates in constant-frequency current-mode control, enabling the use of small, low-profile inductors and capacitors. Its automatic PFM mode improves efficiency at light loads, extending battery life.

Typical protections include undervoltage lockout, thermal shutdown, current limiting, and over-voltage protection, ensuring reliable operation even under demanding conditions. The compact SOT23-6 package makes it ideal for space-constrained power supply designs.
