1994 Burr-Brown CorporationPDS-1250 BPrinted in September, 1995 high - voltage , high -CurrentOPERATIONAL AMPLIFIERDESCRIPTIONThe OPA544 is a high - voltage / High-Current opera-tional Amplifier suitable for driving a wide variety ofhigh power loads. high performance FET op ampcircuitry and high power output stage are combined ona single monolithic OPA544 is protected by internal current limit andthermal shutdown OPA544 is available in industry-standard5-lead TO-220 and 5-lead surface-mount power pack-ages. Its copper tab allows easy mounting to a heatsink for excellent thermal performance.
current and the voltage across the conducting output transis-tor, VS–VO. The power dissipated by the output transistor is equal to the product of the output current and the voltage across the conducting transistor, V S–VO. The Safe Operating Area (SOA curve, Figure 2) shows the permissible range of voltage and current. FIGURE 1.
