MT3608
High Efficiency 1.2MHz
2A Step Up Converter FEATURES GENERAL DESCRIPTION • Integrated 80mΩ Power MOSFET
• 2V to 24V Input Voltage
• 1.2MHz Fixed Switching Frequency
• Internal 4A Switch Current Limit
• Adjustable Output Voltage
• Internal Compensation
• Up to 28V Output Voltage
• Automatic Pulse Frequency Modulation
Mode at Light Loads
• up to 97% Efficiency
• Available in a 6-Pin SOT23-6 Package 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
