Easy-to-implement building blocks simplify SMPS design

Digi-Key now stocks International Rectifier’s µHVIC family which offers a 'tool kit' of ICs for common circuit elements in switched mode power (SMPS) electronics. The family offers engineers simple, flexible ICs with which to conveniently design and innovate. The newest family of µHVIC devices include the IRSxx752L 100V, 200V, and 600V single-channel high-side drivers; the IRS25751L high-voltage start-up IC; the IRS44273L single-channel low-side driver IC; the IRS2505L PFC boost driver IC; and the IR25750L current sensing IC. The IRSxx752L devices are high-side, single-channel gate driver ICs with 600V (IRS25752L), 200V (IRS20752L), or 100V (IRS10752L) blocking and level shifting capability. The IRSxx752L series includes a wide VCC supply range, UVLO protection, and exceptional immunity to harsh dv/dt or –VS switching environments. The series utilizes International Rectifier’s Gen 5 HVIC process which allows for these functions and features to be realized in a tiny 6-pin SOT-23 package, says the company.
