DC DC Converters

DC-DC converters are electrical circuits designed to convert one form of direct current (DC) voltage to another, such as to step up or step down the voltage to an appropriate level. It is often used in automotive, aerospace, renewable energy, consumer electronics and off-grid systems. A few types of DC-DC converters are buck converters, boost converters and buck-boost converters.

V110B5T100B3 Application Field and Working Principle

V110B5T100B3 is one kind of DC-DC converter designed for use in the automotive and aerospace industries. It converts through a two-stage solution varying between 12-24V input voltage range, threhold, and a programmable voltage output range between 0 to 18V (adjustable over an 11-bit register). As its relatively broad input voltage range which aims to provide better performance for lithium-ion battery applications, this converter device makes it especially well suited to use in electric vehicles and new energy vehicle chargers.

The main principle of V110B5T100B3 DC-DC converter can be divided into two stages. First stage is a high-frequency single-ended forward converter: the buck converter, which is used for voltage step-down. Second stage is the topology of basic synchronous rectification, voltage hysteresis modulation, and voltage representation area dimming control: the Boost converter, which is used for an output voltage boost. The overall conversion rate is highly efficient with insignificant energy loss.

The V110B5T100B3 integrated chip includes a high-efficiency MOSFET switching transistor, a low on-resistance, low gate charge, high current, low profile MOSFET output transistor, advanced bus voltage regulation, along with adaptive driving voltage regulation, current limit protection, input shorting or over-voltage protection, output shorting or over-voltage protection, battery under-voltage protection and warning alarms.

The efficiency of V110B5T100B3 DC-DC convert can reach up to 90% when the input voltage is between 12-24V. With its robust performance, low heat generation, high conversion rates and improved working regulations, the V110B5T100B3 DC/DC converter has been widely used in the automotive and aerospace industries.
