Synchronous Step Down Controller

The mp9928 uses pwm current control architecture with accurate cycle by cycle current limiting.

Synchronous step down controller.

Synchronous step down dc dc controllers the ltc 3869 is a high performance dual synchronous step down switching regulator controller that drives all n channel synchronous powermosfetstages. The ic supports current sensing using either an external current sense resistor for accuracy or an inductor dcr for improved system efficiency. The max17558 is a dual output synchronous step down controller that drives nmosfets. 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.

Each controller is available in a lead pb free mlp33 10 package and is specified to operate over a temperature range of 40 c to 85 c. The device uses a constant frequency peak current mode architecture. Analog devices manufactures a broad line of high performance step down buck switching regulator ics and buck switching controller ics with both synchronous and nonsynchronous switches. It is a class of switched mode power supply smps typically containing at least two semiconductors a diode and a transistor although modern buck converters frequently replace the diode with a second transistor used for.

It is capable of drivin. The max17557 is a synchronous step down controller that drives nmosfets. The lm3150 simple switcher controller is an easy to use and simplified step down power controller capable of providing up to 12 a of output current in a typical application. Operating with an input voltage range of 6 v to 42 v the lm3150 controller features an adjustable output voltage down to 0 6 v.

The device can be configured as two single phase independent 10a power supplies or as a dual phase single output 20a power supply. Compare and select from ti s step down buck controllers featuring non isolated switching voltage regulators that require an external mosfet to set the output current to better optimize efficiency and performance in your design. Samples and production quantities of the new synchronous buck step down controller ics are available now with lead times of six to seven weeks for larger orders. A buck converter step down converter is a dc to dc power converter which steps down voltage while stepping up current from its input supply to its output load.

Power loss and noise. The mp9928 is a high voltage synchronous step down switching regulator controller that can directly step down voltages from up to 60v. Qfn 20 3x4 tssop20 ep.
