Description

The PTN78020AAH is a 1-output 25W through hole-mount non-isolated adjustable positive-to-negative Voltage Regulator Module with wide negative output. The PTN78020A is a series of high-efficiency buck-boost-integrated switching regulators (ISR), that represent the third generation in the evolution of high-performance power modules designed for industrial use. The wide-input voltage range makes these modules suitable for a variety of applications that operate off 12, 24V and tightly-regulated 28VDC power. The PTN78020A is smaller and lighter than its predecessors and has either similar or improved electrical performance characteristics. The PTN78020A operates over an input voltage range of 9 to 29V and provides high-efficiency, positive-to-negative voltage conversion for loads of up to 4A. The output voltage is set using a single external resistor and may be adjusted to any value within the range, -15 to -3V.
