  • Description

The PTN78020A is a high-efficiency buck-boost-integrated switching regulators (ISR).The PTN78020A operates over an input voltage range of 9 V to 29 V, and provides high-efficiency,positive-to-negative voltage conversion for loads of up to 4 A. The output voltage is set using a single external resistor, and may be adjusted to any value within the range, –15V to –3V.

For a post-regulated -12VDC the output should be set to -15V and will yield a maximum rating of ~1.6A. For a non-post-regulated -12VDC the output can be set to -12V yielding a rating of over 2A
