SM646 - SWITCHING REGULATOR POWER OUTPUT STAGES

Download the SM646 datasheet PDF. This datasheet also covers the SM645 variant, as both devices belong to the same switching regulator power output stages family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • The SM645/646/647 series of Power Output Stages are especially designed to be driven with standard PWM integrated circuits to form an efficient switching power supply. The SM645, SM646 and SM647 are optimized for non-isolated Buck and Buck-Boost.

SM645/SM646/SM647 SWITCHING REGULATOR POWER OUTPUT STAGES DESCRIPTION FEATURES The SM645/646/647 series of Power Output Stages are especially designed to be driven with standard PWM integrated circuits to form an efficient switching power supply. The SM645, SM646 and SM647 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.
