A DC-DC converter is a device that uses a direct current (DC) input voltage to produce a DC output voltage of either the same magnitude, higher or lower than the input voltage. The V28B36M150BF3 DC-DC converter is an example of a high-performance switching regulator that offers excellent efficiency across a wide input voltage range. This article will provide an overview of the application field and working principle of the V28B36M150BF3 DC-DC converter.

Application Field

The V28B36M150BF3 DC-DC converter is an offline converter designed for applications that require a high DC current, such as automotive, avionics, telecommunications, and high-power LED lighting. It features an adjustable output voltage range of 1.8 V to 36 V with a peak output current of 150 amps. The V28B36M150BF3 is a combination of an active PFC control, a dual-channel synchronous rectification, and a wide input range from 4.5 V to 24 V. With these features, it can achieve a high power factor over 0.9, an efficiency of up to 97%, and a low standby power consumption. It is also designed with Over Temperature Protection (OTP), Under Voltage Lockout (UVLO), thermal shutdown, and over-current protection (OCP).

Working Principle

The V28B36M150BF3 DC-DC converter is based on a continuous conduction mode (CCM) boost converter topology. The input voltage, V IN , is regulated by an active PFC control stage to produce a clean input power. The PFC output voltage, V PFC , is then regulated by the voltage feedback loop. The output voltage range can be adjusted by one external resistor, R SENSE .

The input regulator stage then feeds the power to the high-side converter, which is composed of an H-bridge with two power MOSFETs connected in series and two diodes. The synchronous rectification stage utilizes two N-channel MOSFETs, connected in parallel in the output. The two power MOSFETs in the H-bridge control the current in both directions. The switching and current regulation is provided by a digital control and gate drive circuit, which also provides the protection functions.

The output voltage is sensed by the feedback loop, and the error amplifier is responsible for regulating the output voltage. The output voltage is then regulated by the high-side and low-side converters, which utilize the same switching frequency. The output voltage is maintained despite changes in the input voltage, temperature, and output current.

Conclusion

The V28B36M150BF3 DC-DC converter is a high performance, high efficiency, and low standby power consumption device designed for applications that require a high DC current. Thanks to its adjustable output voltage range, it can be used in a variety of applications. It is based on a continuous conduction mode boost converter topology and utilizes active PFC control, dual-channel synchronous rectification, and protection features to achieve high power factor, efficiency, and protection.
