This document is an application note about the PT5040 series products, introducing the features, working principles and application scenarios of the products.
The Power Trends PT5040 Series is a 3-terminal Integrated Switching Regulator (ISR) packaged in a 3-pin SIP configuration. It is specifically designed for use with +5 volt systems that require an additional regulated voltage ranging from +8 to +20 volts, providing up to 1A of output current.
| Output Current | 1A (typical) |
|---|---|
| Input Voltage Range | +4.75V to +14V |
| Output Voltage Tolerance | -20% to +33% |
| Efficiency | 85% |
| Switching Frequency | 500 to 950 kHz |
The regulator provides regulated outputs from +8 to +20 volts.
No, Boost topology ISRs like this one are not short-circuit protected.
