SM627 General Description

The SM625/626/627 series of Power Output Stages are especially designed to be driven with standard PWM integrated circuits to form an efficient switching power supply. The SM625, SM626 and SM627 are optimized for non-isolated Buck and Buck-Boost application. The hybrid circuit construction utilizes thick film resistors on a beryllia substrate for maximum thermal conductivity and resultant low thermal impedance. All of the active elements in the hybrid are fully passivated.

SM627 Features

· Equivalent to the Unitrode PIC 625, 626, 627
· 15A current capability
· Designed and characterized for switching regulator applications such as Buck, Boost, and Buck-Boost type
· Cost saving design reduces size, improves efficiency, reduces noise and RFI
· High operating frequency (to > 100KHz) results in smaller inductor-capacitor filter and improved power supply response time
· High operating efficiency at 7A typical performance - Rise and fall time < 300ns Efficiency > 85%
· Electrically isolated, 4-pin, TO-66 hermetic case
