FEATURES
Equivalent to the Unitrode PIC 645, 646, 647
15A current capability
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%
HIGH RELIABILITY FEATURES
Available with high reliability processing
DESCRIPTION
The SM645/646/647 series of Power Output Stages are espe-
cially 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.
