Overview
The PTN04050A, produced by Texas Instruments, is a 6-W, 3.3/5-V input, wide adjust output positive-to-negative converter. This integrated switching regulator is designed to provide high-efficiency, positive-to-negative voltage conversion for loads up to 6 W. It operates over a wide input voltage range of 2.9 V to 7 V and offers an adjustable output voltage from -15 V to -3.3 V, set using a single external resistor. The PTN04050A is smaller and lighter than its predecessor, the PT5020 series, with improved electrical performance characteristics and thermal management. It is compatible with TI's roadmap for RoHS and lead-free compliance.
