Featured by Allegro MicroSystems Europe for the first time at PCIM in Nuremberg in May will be a new family of power-supply IC modules from parent company Sanken The new STR-T2200/STR-T4200 series use a patented partial current resonant topology which is ideally suited to low-output-voltage, high-power applications such as 200W LCD TV power supplies, 200W adapter power supplies and 1kW DC/DC convertors for automotive applications

Integrated switching regulators cut PSU cost
Allegro Sanken now offers a range of integrated high-voltage switching regulators which allow the designer to produce the lowest-cost switch-mode power supply possible
The new topology results in extremely high efficiency and very low noise.
Also featured is Allegro's ACS750 family of fully integrated current sensors, offering high-power current sensing at current ratings of up to 100A from a very compact package.
The unique current sensing assembly includes a high current conductor, ferrite core, and an optimised monolithic Hall IC in the smallest integrated current sensing package in the industry.
The magnetic field, created by the current passing through the ultra-low-resistance power lead frame, is concentrated by a ferrite core and measured by the sensing element of the Hall IC.
Factory programming of the Hall IC provides high accuracy and linearity over temperature, and the optimised package design achieves high dielectric isolation.
