Enable more efficient power conversion in your higher frequency switching applications with Allegro MicroSystems’ ACS37002 - the world’s most accurate 400kHz current sensor IC with 5kV isolation rating. Eliminating compromise between speed, accuracy and power density, the new family of Hall-effect current sensors have integrated features that simplify design and reduce system size - available in three easy-to-use surface-mount package...

The LMR36506 is the industry’s smallest 65V, 0.6A synchronous step-down DC/DC converter in 2x2mm HotRod package. This robust and highly reliable converter can handle input voltage transients up to 70 V, provide excellent EMI performance and support fixed 3.3 V and other adjustable output voltages. 

The LM1117 is a low dropout voltage regulator with a dropout of 1.2V at 800mA of load current. The LM1117 is available in an adjustable version, which can set the output voltage from 1.25-13.8V with only two external resistors. In addition, it is available in five fixed voltages, 1.8, 2.5, 3.3 and 5V. The product offers current limiting and thermal shutdown. Its circuit includes a Zener trimmed bandgap reference to assure output voltage...

This reference design is a simple, wearable, multi-parameter, patient monitor that uses a single-chip, biosensing front end, the AFE4900 device, for synchronized electrocardiography (ECG) and photoplethysmography (PPG) measurements. The measured data is transferred to a remote location using the CC2640R2F device (supporting BLE 4.2 and 5). 

This reference design implements Class 0.5 single-phase energy measurement using standalone multi-channel analog-to-digital converters (ADC) to sample a shunt current sensor. With the combination of the shunt sensor and a compact magnetically immune power supply, the design provides protection against magnetic tampering attacks.

A power delivery network of DCM DC-DC converters can be used independently or with downstream point-of-load ZVS buck and buck boost regulators to support efficient power delivery. These scalable, high efficiency DC-DC converters also provide superior power system performance and connectivity from a variety of unregulated power sources to the point of load.

The TPS546D24A is a highly integrated, non-isolated DC/DC converter capable of high frequency operation and 40A current output from a 7-mm × 5-mm package. Two, three, and four TPS546D24A devices can be interconnected to provide up to 160 A on a single output. The device has an option to overdrive the internal 5-V LDO with an external 5-V supply via the VDD5 pin to improve efficiency and reduce power dissipation of the converter.

This reference design enables a wearable, optimized saturation of peripheral capillary oxygen (SpO2) and multi-sensor, multi-wavelength optical heart rate monitor (HRM). It uses AFE4420 device, which is a single-chip, bio-sensing front end for photoplethysmography (PPG) measurements. It supports up to four switching light-emitting diodes (LEDs) and up to four photodiodes to enable signal acquisition of up to 16 Phases.
