Synchronous Step Down Controller

Power loss and noise.

Synchronous step down controller.

The max17557 is a synchronous step down controller that drives nmosfets. The max17558 is a dual output synchronous step down controller that drives nmosfets. The device features a peak current mode constant frequency architecture allowing it to operate up to 2 2mhz. 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.

The ic supports current sensing using either an external current sense resistor for accuracy or an inductor dcr for improved system efficiency. 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. The mp9928 uses pwm current control architecture with accurate cycle by cycle current limiting. 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 mp9928 is a high voltage synchronous step down switching regulator controller that can directly step down voltages from up to 60v. 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. 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 constant frequency current mode architecture allows a phase lockable frequency of up to 780khz.

Frequency adjustable hiccup current limit. 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 device can be configured as two single phase independent 10a power supplies or as a dual phase single output 20a power supply. 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. 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. 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.
