Step Up Voltage Regulator Ic

Analog devices manufactures a broad line of high performance step up boost switching regulator ics and boost switching controller ics with both synchronous and nonsynchronous switches.

Step up voltage regulator ic.

Polarity inverting switching regulatory as shown in the figure above when the transistor is saturated the current flows through the inductor. Step up voltage regulator with lm2577. A capacitor inductor or the two in combination. The ic has a wide input voltage range 3 5v to 40v and is available in different output voltage versions.

Step up switching converters also called boost switching regulators provide a higher voltage output than the input voltage. 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 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. Boost converters which can step up the voltage without increasing the number of cells power.

Many of our step up switching regulators are designed for driving strings of leds. It has an internal 0 17 ω n channel mosfet power switch.

The battery s usable output varies from about 1 8 v to 3 4 v whereas the ics require 1 8 v and 5 0 v to operate.

12v 15v and adjustable. Figure 1 shows a typical low power system powered from two series connected aa batteries. The lm2577 integrated circuit from national semiconductor is a useful ic that provides all of the power and control functions for a simple boost step up flyback and forward converter switching regulator. The lm2621 is a high efficiency step up dc dc switching regulator for battery powered and low input voltage systems.

This extensive portfolio includes synchronous and non synchronous devices that address applications ranging from milliamps up to 100 a with efficiencies as high as 96 and include key features such as wide input voltage operating range wide v in low quiescent current i q for extended battery life and adjustable frequency with external synchronization to help manage switching noise. The output voltage is regulated as long as the power draw is within the output power specification of the circuit. It accepts an input voltage between 1 2 v and 14 v and converts it into a regulated output voltage. These switching voltage regulators offer typical input voltage capability from less than 2 v up to 100 v switching frequencies up to 4 mhz and high efficiency op.
