Overview
The PTN04050AAZ, produced by Texas Instruments, is a high-performance, 6-Watt, positive-to-negative integrated switching regulator. This component is designed to provide efficient voltage conversion for a wide range of applications. It operates over a wide input voltage range of 2.9 V to 7 V and can adjust the output voltage from -15 V to -3.3 V using a single external resistor. The PTN04050AAZ is smaller and lighter than its predecessor, the PT5020 series, with improved electrical performance characteristics and enhanced thermal properties. It is suitable for various general-purpose applications, including industrial controls, HVAC systems, test and measurement, medical instrumentation, and more.
