Demonstration circuit 3051A features the LTM4705, a high efficiency dual 5A or single 10A μModule® DC/DC regulator in a compact and low profile 6.25mm × 7.5mm × 3.22mm BGA package. The LTM4705 can take 3.1V to 20V input and generate 0.6V to 5.5V output (stepdown only). The DC3051A demo board is designed to take 6VIN to 20VIN to dual 5A jumper selectable outputs. The board operates by default at a fixed 1MHz and can be synchronized from 1MHz to 3MHz via the MODE/SYNC pin. With its high switching frequency and current mode architecture, a fast transient response to line and load changes is possible without sacrificing stability. The DC3051A can be used in forced continuous mode or pulse-skipping mode for low noise, or in Burst Mode® operation for high efficiency at light loads. Please see the LTM4705 data sheet for more detailed information. It is recommended to read the data sheet for the LTM4705 prior to making any changes to the DC3051A.

The ADA4571-2 is a 2-channel anisotropic magneto resistive (AMR) sensor with integrated signal conditioning amplifiersand ADC drivers. The device produces analog outputs that indicate the angular position of the surrounding magnetic field.Each channel consists of two die within one package: an AMR sensor and a variable gain instrumentation amplifier. The ADA4571-2 delivers clean and amplified cosine and sine output signals per channel related to the angle of a rotating magnetic field. The output voltage range is ratiometric to the supply voltage.Each sensing channel contains two separated wheatstone bridges at a relative angle of 45? to one another. A rotating magnetic field parallel to the plane of the IC package delivers two sinusoidal output signals, with the double frequency of the angle, ?, between the sensor and the magnetic field direction. Within a homogeneous field parallel to the plane of the IC package, the output signals are independent of airgap between the sensor and the magnet.The ADA4571-2 is available in a 16-lead SOIC package.Product Highlights Contactless angular measurement. Measures magnetic field direction rather than field intensity. Minimum sensitivity to air gap variations. Large working distance. Excellent accuracy, even for weak saturation fields. Minimal thermal and lifetime drift. Negligible hysteresis.Single-chip solution.Applications Permanent magnet synchronous motor (PMSM) control and positioning Contactless angular measurement and detection?

The LT8602 is a quad channel, current mode, monolithic buck switching regulator with a programmable power-on reset. All regulators are synchronized to a single oscillator with an adjustable frequency from 250kHz to 2.2MHz. The LT8602 can be configured for micropower Burst Mode operation or pulse-skipping operation at light load. Micropower operation results in quiescent current of 30?A with all four regulators operating in the application below.The high voltage channels are synchronous buck regulators that operate from an input of 3V to 42V. The output currents are up to 1.5A (OUT1) and 2.5A (OUT2). The low voltage channels operate from an input of 2.6V to 5.5V. Internal synchronous power switches provide high efficiency with output currents up to 1.8A. The LT8602 uses a 2-phase clock with channels 1 and 3 operating 180? from channels 2 and 4 to reduce input ripple current on both HV and LV inputs. All channels have cycle-by-cycle current limit, providing protection against shorted outputs.
