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–V, 24–V, and tightly-regulated 28–V dc power. In new designs, they should be considered in place of the PT6640 and PT78NR100 series of single in-line pin (SIP) products. The PTN78020A is smaller and lighter than its predecessors.
The PTN78020A is a high-efficiency buck-boost-integrated switching regulator (ISR) designed for industrial use. It operates over an input voltage range of 9 V to 32 V and provides high-efficiency positive-to-negative voltage conversion for loads up to 4 A.
The output voltage can be adjusted from -15 V to -3 V using a single external resistor. The module features undervoltage lockout, overtemperature shutdown, and is available in surface-mount packages compatible with RoHS compliance.
