The MT3608 Boost DC-DC voltage regulator is a constant frequency, current mode step-up converter intended for small, low power applications that boosts any input voltage of 2V to 24V to an output voltage of ~3V to 28V .
The MT3608 device switches at 1.2MHz and allows the use of tiny, low cost capacitors and inductors to minimize the overall module size. Internal soft-start circuitry results in small inrush current and extends battery life.
The MT3608 features automatic shifting to pulse frequency modulation (PFM) mode at light loads. It includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload.
MT3608 Specifications:
Maximum output current: 2A
Input voltage: 2V ~ 24V
Maximum output voltage: 28V (Output voltage must be greater than input voltage)
Maxiumum efficiency: Up to 97%, typically 93% at Vout=12V, Vin=5V, Iout=200mA
Dimensions: 36 mm * 17 mm * 6 mm
Operating Instructions:
Connect the Vin+ and Vin- to +2V to +24V DC. A battery or +5V USB power supply are optimal voltage sources.
Connect the Vout+ and Vout- to an appropriate load.
Adjust the potentiometer to vary the output voltage. Turn counter-clockwise to increase voltage. Upon initial operation, several counter-clockwise turns of the pot are needed to achieve a boosted output voltage.
Input voltage should not exceed 24V maximum input voltage.
Output voltage should not exceed 28V maximum output voltage.
Output voltage level must be greater than input voltage level.
Peak output current should be limited to 2A maximum.
