This document introduces the PT5020 series of integrated switching regulators (ISRs), which convert a positive input voltage to a negative output voltage for a wide range of analog and datacom applications. These Plus to Minus ISRs incorporate a “Buck-Boost” topology and are packaged in the 3-pin, single in-line pin (SIP) package configuration.
The document describes the PT502x series of Positive Input/Negative Output Integrated Switching Regulators (ISRs). These devices convert a positive input voltage to a negative output voltage using a Buck-Boost topology. They are designed for analog and datacom applications and feature laser-trimmed accuracy, soft-start capability, and small footprints available in 3-pin SIP packages.
| Output Current (Typical) | 0.65 A |
|---|---|
| Switching Frequency | 1.7 to 8 MHz |
| Operating Temperature Range | -20 to +85 °C |
No, the PT5020 ISRs are not Short-Circuit Protected.
The device operates with a positive input voltage ranging from +4.75 to +7 Volts.
