A boost converter ( step-up converter ) is a DC-to-DC power converter that steps up voltage (while stepping down current) from its input (supply) to its output (load). It is a class of switched-mode power supply (SMPS) containing at least two semiconductors (a diode and a transistor) and at least one energy storage element: a .

The buck– boost converter is a type of DC-to-DC converter that has an output voltage magnitude that is either greater than or less than the input voltage magnitude. It is equivalent to a flyback converter using a single inductor instead of a transformer. Two different topologies are called buck– boost converter.
Often, although a DC supply, such as a battery may be available, its available voltage is not suitable for the system being supplied. For example, the motors used in driving electric automobiles require much higher . How boost converters work and how to build a 50W adjustable boost converter circuit. Linear Technology manufactures a broad line of high performance step-up boost switching regulator ICs and boost switching controller ICs with both synchronous and non-synchronous switches. The buck- boost converter is based on a fixed frequency, pulse width modulation ( PWM) controller using synchronous rectification to obtain maximum efficiency. At low load currents, the converter enters power-save mode to maintain high efficiency over a wide load current range.
The power-save mode can be disabled , . The ST8Ris a step-up DC-DC converter featuring an output current cut-off function. This boost converter is ideal for use where designers have tight constraints in terms of PCB area and cost. The basic concept of operation is that every time the switch is close current builds up in the inductor.
If the switch is closed again, . The board is configured to be used with a LiPo battery, has solder jumper selectable 5V and 3. V output, and an under voltage protection of 2. However, the board can also be used as a general purpose buck and boost regulator with an . The resulting merged topology stacks secondary-winding flyback voltage on top of the input voltage and the primary-winding flyback voltage (a standard flyback converter only takes advantage of flyback voltage produced at the secondary side). Compared with a standard boost converter ,this topology produces higher output . A detailed disscussion of the relative merits of inductor based boost converters and capacitor based charge pumps for powering white LEDs in portable equipment. Specific circuits are shown.
